Report of
FNCA 2011 Workshop on Neutron Activation Analysis Project
November 21-24, 2011
Sydney, Australia
FNCA 2011 Workshop on Neutron Activation Analysis (NAA) was held from November 21 to 24 2011, in Sydney, Australia. This Workshop was hosted by Australian Nuclear Science and Technology Organisation (ANSTO) and Ministry of Education, Culture, Sports, Science and Technology (MEXT) of Japan.
The NAA Workshop was attended by 15 participants from 11 FNCA member countries, namely Australia, Bangladesh, China, Indonesia, Japan, Kazakhstan, Korea, Malaysia, the Philippines, Thailand and Vietnam including workshop staffs.
This project enters the fourth phase in this year. Neutron activation analysis is an elemental analysis method by measuring the radioactivity and gamma-ray energy of radionuclides produced by neutron irradiation of target samples. This method has an excellent analytical capability of simultaneously and non-destructively determining multiple elements in the sample. The current project consists of three subprojects (shown below) in which scientific as well as socio-economic contributions are aimed by utilizing NAA technique.
The workshop consisted of the following six sessions. Each country presented the progress in corresponding session(s).
Session 1: NAA of geochemical samples for geochemical mapping and mineral exploration (subproject 1),
Session 2: NAA-related presentations,
Session 3: NAA of food samples for contamination-monitoring (subproject 2),
Session 4: NAA of marine sediment samples for environmental monitoring (subproject 3),
Session 5: General discussion and summary of the 2011 workshop, and
Session 6: Drafting of minutes.
In finalizing the workshop, we discussed two issues, namely the linkage between NAA people working at research reactors and end-users (users outside of reactor facilities) and the alliance of NAA users in Asia/Oceania. The objective of this discussion is to expand our activity of NAA in near future. The discussion will be continued in coming years,
Technical Visit
On November 24, after the completion of all sessions, participants of FNCA workshop visited the ANSTO facilities, including the OPAL research reactor, neutron beam line instruments and the accelerator center.

Preface :
The neutron activation analysis (NAA) project is one of research reactor-related projects in the FNCA activity. Past workshops have been held jointly with the research reactor technology (RRT) project workshop but the 2011 FNCA workshop on NAA was held separately for the first time. During the opening session, the project leader Prof. M. Ebihara (Japan) presented an overview talk entitled "Scope of the 2011 workshop on NAA". The session was closed with the self-introduction of participants.
The workshop consisted of the following 6 sessions:
Session 1: NAA of geochemical samples for geochemical mapping and mineral exploration,
Session 2: NAA-related presentations,
Session 3: NAA of food samples for contamination-monitoring,
Session 4: NAA of marine sediment samples for environmental monitoring,
Session 5: General Discussion and Summary of the 2011 workshop, and
Session 6: Drafting of minutes.
The following draft summary of the presentations and discussions in sessions 1 to 5 were finalized in the final session (session 6).
After the completion of all sessions, we enjoyed a technical tour of the ANSTO facilities, including the OPAL research reactor, neutron beam line instruments and the accelerator center with an excellent tour guide.
Summary :
Session-1: NAA of Geochemical Samples for mapping and mineral resources exploration
Australia
A number of projects that had been carried out by ANSTO involving measurements of geochemical samples were described. The end-user groups included university researchers, reference material producers and the mining industry. The end-users valued the consistency of NAA results used for constructing extensive databases and also the ability to measure 'difficult' elements such as chlorine in iron ore. In the near future a meeting will be held with Geoscience Australia to promote the use of NAA in national geochemical mapping programs.
Bangladesh
Bangladesh has analyzed 25 sediment samples collected from the bank of Karnaphuli River. The analysis of the samples revealed that the investigated Karnaphuli River sediments are highly contaminated with As, Cr, Co and Cr. The geochemical association of Cr, Co, Rb in the sediment shows that these metals are deposited from anthropogenic sources. The number of investigated samples was not enough to draw firm conclusions. Intensive study in a systematic way is required to draw final conclusions.
China
Three kinds of procedures for U, Th and K determination have been studied by using INAA. More than 700 geological samples have been analyzed for the purpose of Optically Stimulated Luminescence Dating.
Indonesia
Geochemical mapping of Ce, Co, Eu, Fe, La, Nd, Sc, Sm, Hf and Yb in Serang District and Cilegon City have been successfully obtained by k0-NAA combined with GIS software. It has been found that there has been no enrichment of these elements compared with crustal abundances so it can be concluded that there is no significant contribution from anthropogenic sources.
Japan
As no new data are available for 2011, some statistical calculations were made by using a large number of data obtained by NAA in previous years, yielding several interesting findings. It has been confirmed that NAA is a powerful and advantageous analytical tool for geochemical samples.
Malaysia
An in-house geochemical reference material has been analyzed by using INAA and initial data consisting of 31 elements have been reported. In future, INAA and other analytical techniques will be used to obtain more elemental data for this reference material.
Summary of Discussion - Sub-project NAA-1: NAA of Geochemical Samples
All participating countries demonstrated different approaches to addressing the intended aims of the sub-project. Australia's main theme was in using NAA to service the needs of the mining industry for the production of reference materials and quality assurance measurements. Bangladesh took the opportunity to 'map' the levels of elemental pollutants in sediment along a river estuary. China described a large project to measure K, Th (by NAA) and U (by DNAA) to enable thermoluminesce dating of geological materials. Indonesia produced a geochemical map of different elements in large region of Serang-Banten province to look for evidence of enhanced levels of pollutants that might be due to industry. Due to the interruption of reactor availability in Japan, previous geochemical mapping data were re-analyzed to determine correlations between different elements to provide insights into their source - natural weathering or human activities. Malaysia measured a large number of samples from mining activities and provided reliable data to government authorities for evaluation of possible impact of mineral processing.
It can be observed that all the projects involved engagement with end-users in each of the participating countries, including nationally important industries and government regulatory agencies. This is a satisfying demonstration that a key objective of the sub-project is being achieved - through increased engagement with end-users there is a greater awareness of the capabilities and strengths of NAA and this should lead to a greater utilization of research reactor facilities. All participants are encouraged to continue to move in this direction.
Activities for the coming year were discussed. It was agreed that in addition to individual country projects responding to national needs, there would be a unifying task to re-examine the characterization of Japanese stream sediment reference materials, JSd-1, -2 and -3. Very good information was obtained in the first proficiency test and the results have been presented at an international conference and published in a scientific journal. The delegates felt that another round of measurements would improve the characterization of the materials and enhance their usefulness as reference materials for use in FNCA projects. The task would provide the opportunity for participating countries to demonstrate an improvement in their performance, satisfying another aim of the sub-project which is to improve the capabilities of NAA laboratories within the FNCA.
It was agreed that the measurement and reporting protocols would be more tightly specified in this round, after consultation with experts in the field of reference material production and proficiency testing.
- Plans for next year of NAA-1
Australia will attempt to expand the end-user group by discussing opportunities for joint projects with Geoscience Australia. Bangladesh will continue the program of analyzing sand from Cox's Bazaar, characterizing the results by location, depth and particle size. Next year China will focus on the foodstuffs sub-project but will respond to any demand from end-users for geochemical analysis. Indonesia will continue working on the 5-year program to carry out geochemical mapping in Serang-Banten province. Kazakhstan will join the sub-project and will be involved in the analysis of ores from the mining industry. Malaysia will be engaged in regular analysis of mining wastes for government regulators and will make contact with the Mineral and Geoscience Department to investigate opportunities for NAA. Japan will continue work on the regional geochemical mapping using stream sediments, depending on the availability of research reactors.
Session-2: NAA-related presentations
Country Report (Kazakhstan)
The NAA group that is a part of the Complex Ecological Research Centre (CERC) participates in two activities: 1) Elemental analysis of the territory of the Semipalatinsk Nuclear Test Site (STS) for finding solutions for remediation of the most impacted territories of STS; 2) Radioecological inspection and monitoring of trans-boundary rivers of Kazakhstan lead by Dr. V.Solodukhin under the "NAVRUZ" international project. Laboratory works are carrying out under ISO 17025. Future activity of the NAA group is focused on the development of techniques to perform routine instrumental NAA for the determination of Rare Earth Elements (REE) in different types of ore. Under IAEA TC KAZ/8/006 a new pneumatic transport system was purchased and will be installed in 2012 to strengthen the capabilities for REE analysis.
IAEA-CRP (Australia)
John Bennett provided information on a proposed IAEA CRP on automation in NAA facilities. Expected outcomes of the 4-year project include an improvement in the number of samples that can be measured each year, with a consequent increase in revenue and utilization of research reactors. The documents to initiate the CRP are expected to be issued in December and the first meeting of the selected participants may be held around June 2012 in Delft.
Session-3: NAA of Food Samples for contamination-monitoring
China
Twenty-nine elements in ten kinds of biology reference materials were determined using thermal and epithermal NAA for inter-comparison. The interferences from threshold reactions and sum-peaks were considered. These biology RMs will be used for contamination monitoring of food stuffs.
Indonesia
Determination of toxic and essential elements in foodstuff samples by k0-INAA has been done. Samples of unpolished rice, vegetables, legumes, flour, fish and meat were used. Samples were collected from a market in Serang City, Banten Province, Indonesia, using a market basket method. The results show that foodstuff samples contain macro levels of K, Mg, Na and Cl and micro levels of Fe, Mn, Zn, Cr, Br, Rb, Co, Cr and La. Toxic elements Hg and As were found in some foodstuffs. The concentration of essential elements in unpolished rice was found to be greater than in polished rice. The content of the toxic element As in eggs, golden fish and wheat flour was found to exceed permissible limit values.
Japan
Six samples of tea leaves were analyzed by INAA and PGA (neutron-induced prompt gamma-ray analysis). A total of 18 elements were quantified, among which H, B, Si and Cl were determined by PGA. The non-destructivity and the ease of sample preparation as well as the reliability of INAA and PGA results showed that these analytical methods are highly advantageous when analyzing solid samples.
Korea
Analytical results of 4 sorts of unpolished rice and 3 sorts of beans were presented. As expected, the concentration of most elements were found to be higher in beans than in unpolished rice, except for As.
Malaysia
Two types of fish samples were analyzed using INAA for trace elements (Cr, Hg, Se and Zn). It was found that the dietary intake of Hg was higher than EPA guideline.
The Philippines
Philippine and Japan polished rice samples analyzed by INAA showed reduction by as much as 72-91% for Na, Mg, Mn and K and by as much as 27% for Ca and Zn, compared with unpolished rice. As levels were below the maximum allowable limit in China. A very high level of Br in one Philippine rice sample which exhibited a δ13C signature (analyzed by IRMS) outside the range of other Philippine rice samples may indicate this particular sample being an imported rice which had been exposed to the pesticide methyl bromide during quarantine.
Thailand
Six varieties of beans were bought from three local markets in Bangkok, Thailand, and were analyzed by INAA using the relative comparator technique. Three minor (Ca, K, Mg) and eight trace elements (Al, As, Br, Cl, Cu, Fe, Mn, Zn) including precision, accuracy and detection limits for each element were determined in this study.
Vietnam
13 nutrient and toxic elements in 18 types of popular rice collected in the south of Vietnam were determined by NAA and AAS. The daily intake of most elements were found to be within safe limits, except for As and Cl.
Summary of Discussion - Sub-project NAA-2: NAA of Food Samples
In last workshop, a common target for food samples was not decided. Nevertheless, eight participating countries in this subproject have presented the analytical results of a diverse range of foodstuffs including unpolished rice, green tea, rice, fish, beans, etc. For this new phase of the FNCA project, it was decided after discussion to target common samples which are beneficial and have socio-economic impact in the participating countries. In general, food items can be categorized into some groups - grains, vegetables, meat, fish, fruit, etc. Through sincere discussion, fish was selected as a common target sample. However, it was not easy to nominate particular fish species due to the different marine environments between countries.
Therefore, we agreed that fish species which are popular and representative in each country, are to be selected. A sample treatment protocol will be prepared and provided by Mr. Moon, Korea. In order to collect and compare analytical data between countries, toxic and essential elements including Cr, As, Hg, Sb, Cd, Ca, Se, Zn, shall be analyzed by NAA and other techniques. On the other hand, each country will carry out research work which has socio-economic impact, and present the results and benefits at the next FNCA workshop.
Participating countries: Bangladesh, China, Indonesia, Korea, Japan, Malaysia, The Philippines, Thailand, Vietnam.
Session-4: NAA of marine sediment samples for environmental monitoring
Bangladesh
As agreed at the FNCA workshop 2010 held in Beijing, "NAA of marine sediment samples for environmental monitoring" was adopted for the third phase. We have collected 18 sediment samples from 3 locations at 9 meter (30 feet) intervals at 6 depths, covering 27 meters (90 feet) along the bank of the River Buriganga from Hazaribag sluice gate area. However, the 3 MW TRIGA Mark-II Reactor has been shut down since March 2011 for the replacement of the analogue console with a digital one. We hope to irradiate and analyse the collected sediment samples by March 2012.
Japan
The protocol for core sampling method which was recommended as a common sampling method was presented. Core samples collected at a dredged area in Tokyo Bay were analyzed using INAA. Decreasing hypoxia over the past 30 years was proven by the behavior of Th/U and Ce/U ratios in the sediments. The application of Multiple Prompt Gamma-ray Analysis (MPGA) to marine sediments near the hydrothermal mound was also presented.
Malaysia
Marine sediment samples have been analyzed using INAA. Toxic elements (As, Cr, Sb and Zn) have been evaluated using Potential Ecological Risk Index (PERI). The PERI values of marine sediments showed low risk to humans and the aquatic ecosystem.
The Philippines
The approximate beginning of increased levels of correlated elements of Cu, Fe, Zn and Pb (analyzed by EDXRF) in Core I sample from Manila Bay can be associated with the 1991 Mt. Pinatubo eruption based on available sedimentation rate data by 210Pb determination. INAA is a very powerful tool in distinguishing elemental levels for the characterization of marine sediment samples such as in the case of Manila Bay versus Sorsogon Bay. Manila Bay showed higher concentrations of Na, Mg, Al, Mn, Ti, Cl and V in the top 7 cm core samples than those from Sorsogon Bay. Calcium was at comparable levels in both sites and Al levels were higher in Sorsogon Bay.
Vietnam
29 elements in 46 sediment samples collected at Ganhhao estuary were characterized by NAA. The results showed that for the offshore sample, there was no evidence of pollution. For the surface samples near the shore, pollution was found at low and medium level.
Summary of Discussion - Sub-project NAA-3: NAA of marine sediment samples
Summary discussion was chaired by Prof. M. Matsuo and Dr. K. Naher.
Firstly, the achievement of each participating countries was discussed. In the last workshop, the possibility and necessity of core sampling was discussed as it gives historical information about contamination. On the other hand, a large sampling area can be covered through the analysis of surface sediment. In this case it is not necessary to stick to core sampling. In this workshop the following four countries presented the analytical results of core samples: Bangladesh, Japan, The Philippines and Vietnam. Malaysia presented the results of surface samples collected from all around the coastline of Malaysia. In the second year of the third phase, it has been agreed that each country may continue the analysis of sediment samples according to their own interests, preferably using the recommended core sampling method.
Secondly, application of 210Pb dating method to core samples was discussed. In two countries the 210Pb dating method was used to determine the sedimentation rate. It is hoped that this method could be adopted as a common protocol among FNCA countries. Because it is difficult to measure low energy γ-rays using conventional Ge detector, international collaboration on dating may be helpful.
Thirdly, the possibility of using stream sediments JSd-1, 2 and 3 as standards for quality control was discussed. These reference materials have been used for the laboratory inter-comparison measurements in sub-project 1 and are planned to be re-measured. The use of these well-characterized standards in sub-project 3 would demonstrate concrete benefits arising from a linkage between the geochemical and marine sediment sub-projects.
Fourthly, we discussed various kinds of pollution indexes. For example, Vietnam applied the Enrichment Factor and Geoaccumulation Index to their samples, and Malaysia applied Potential Ecological Risk Index. We agreed to apply these indexes to evaluate our own samples as a trial. Application of the same index to a wide variety of marine sediments may provide an international comparison of contamination levels in the marine environment.
The following six countries showed their interest in working on sub-project 3: Bangladesh, Indonesia, Japan, Malaysia, The Philippines and Vietnam. Among them, Indonesia joined the sub-project but with a focus on river sediment and surface soil for environmental monitoring in accordance with their national interest.
Session-5: General Discussion and Summary of the 2011 workshop
Characterisation of NAA facilities in the OPAL multi-purpose reactor
The start-up of the new OPAL reactor saw the introduction of the k0-method of standardisation for NAA. This required the neutron spectrum of the irradiation positions to be characterised for f (thermal-epithermal flux ratio) and α (epithermal spectrum correction factor). All irradiation positions of interest were found to have very high thermal-epithermal flux ratios, although making precise measurements of these factors proved challenging as a result of this.
General Discussion
In finalizing the workshop, we discussed two issues in this session, namely the linkage between NAA people working at research reactors and end-users (users out of reactor facilities) and the alliance of NAA users in Asia/Oceania. The objective of this discussion is to expand our activity of NAA in near future. The discussion outlines are summarized as follows;
(1) Linkage of NAA people at reactor facilities with NAA users outside of such facilities
At the beginning of the discussion, all participants explained their current situations surrounding them in terms of the linkage between inside and outside users of NAA. As expected, the situation varies from country to country. Dr. Bennett presented an example of successful networking between ANSTO and various end-users in Australia. Mr. Berezovskiy introduced the case of Kazakhstan where he often visited mining companies to discover potential applications of NAA. In other countries, fairly strong and stable relationships between NAA people at research reactors and end-users of research reactors have also been established, but the outreach action seemed to be less active compared with these two countries mentioned above. For expanding the NAA activity, it is highly desired for NAA people working at research reactor facilities to make the outreach effort for establishing functional and effective linkage with outside users, in the industry, government and university sectors.
(2) Alliance of NAA users in Asia/Oceania
Another way to strengthen the NAA activity in our community could be to establish an alliance between countries participating in the FNCA. Before discussing this matter, we heard each participant presenting the current activity of NAA in terms of the number of heavy and soft users of NAA in each country, and acknowledged a large variety in such an activity among countries participating in the workshop. Japan and Korea have associations devoted to NAA named JAAA (Japan Association of Activation Analysis) and KAAA (Korean Association of Activation Analysis). Although no such an organization exists in China, a biannual meeting on NAA is held. In Indonesia, an NAA seminar is held annually through the support of BATAN. In near future, an NAA alliance could be established with participants of the FNCA/NAA workshop as core members. The discussion will be continued in coming workshops.
