1. NAA applications in Mongolia
FNCA Workshop on Neutron Activation Analysis November 2015, Daejeon, South Korea
Efforts for promotion of NAA and establishment of linkages with appropriate end-users of NAA
NAA applications in Mongolia

2. Introduction Mineral resources: Environmental pollutions: Food safety:
Au, W, Ag, Cu, Mo, Fe, CaF2, U, REE
Environmental pollutions:
Air pollution
Soil and sediment
Food safety:
Food products
Soil, plants, fodders
Our NAA possibilities are limited by this neutron flux.
We have a policy to obtain a research reactor.

3. NAA applications
NAA has been used to determine gold, copper, silver, arsenic, uranium, rare-earth elements and heavy metals in geological and environmental samples.

4. Potential end-users for NAA in Mongolia
Mining companies
Environmental monitoring organizations
Inspection Agency
For PT of certification of reference materials

5. MAIN MINING COMPANIES
Erdenet Mining Corporation (EMC) – copper molybdenum mining
Oyu Tolgoi mine – copper and gold mining
Koje Gobi –AREVA – uranium mining
Mongolian other coal and gold mining companies

6. Mining companies interested in:
Elemental analysis in geological and ore samples
To assess the impact of the contamination from the industrial and mining processing activities.
Workplace monitoring and occupational health studies (hair, nail ….)

7. Environmental monitoring organizations interested in:
To determine concentrations of heavy metals and other trace elements in environmental samples (water, soil, plants and sediment samples)
Biomonitoring air pollution in capital and industrial cities through trace-elements and radionuclides: temporal and spatial trends
To detect the source of contamination of the environment

8. Inspection Agency interested in:
Use of INAA in studying health impacts of toxic elements consumed through foodstuffs contaminated by industrial activities in Mongolia
Use of INAA in elemental analysis of some Mongolian medicinal plants
Use NAA for control of the import products such as foods and construction materials

9. Certification of reference materials and PT at Central Geological Laboratory

10. 1973-1991 starting phase of C(RM) production
In 1973 CGl participated in the international project “Production of RMs for mineral resources” (Council of Mutual Economic Assistance )
participation in more then 50 certification projects
1980 first own certification for fluorspar CRM of Mongolia
Production of 9 C(RM)s according to GOST and SEV standards
Achievements:
C(RM) certificates used as proof document for export of mining products of Mongolia
Possibility to use C(RM)s for internal analytical control purposes at CGL
In 1990 the external control analysis abroad was stopped

11. second phase
Production of C(RM)s for quality control purposes for mining and geology section of Mongolia
Project “Production of C(RM)s from mineral resources”
Main objectives:
- to increase type and number of Mongolian RMs
- to increase the number of certified parameters
-to find more laboratories qualified for
certification analyses
Achievements:
- 26 C(RM)s and 21 quality control materials developed according to the GOST standards
Implementation of joint reference material projects, especially with BGR and IAG
Participation in GeoPT scheme
Accreditation according to the ISO/IEC by German accreditation body DAP in 2005

12. Since 2007 third phase Production of CRMs in accordance with
ISO standards and marketing of CGL CRM
at the international and domestic market
Mongolian- German joint project “Certification of reference materials”
- Modernization of preparation laboratory and equipment
- Development of advanced sample preparation methods
- Introduction and strict implementation of the ISO-Guide 30 series standards
- Training of staff members for all relevant certification aspects
- Introduction of specialized software for statistical evaluation
- Networking with relevant international CRM organizations
- Development of CRM marketing strategies

13. CGL established good and long-term basis for organization of proficiency testing within geological and geochemical laboratories operating the country as well in abroad.
CGL is accredited against ISO/IEC as PT provider by the ANSI-ASQ ANAB – American National Accreditation Board recently in June, 2015
So CGL has got THREE accreditations that
is called as “PLATINUM ACCREDITATION”.

14. The first PT scheme at CGL
Feasibility study, decision and planning:

We invite your laboratories to participate our next PT rounds

18. FUTURE PLAN
1. Air pollution study using moss biomonitoring technique in capital and other industrial cities.
We collected 45 moss samples from 5 sites south part of Ulaanbaatar city. Analysis is starting at IBR-2M reactor in Dubna.
Results of this study will be discuss in the 29th Task Force Meeting, 29 February – 4 March 2016, Dubna, Russian Federation.
This study will be continued in samples from other parts of Ulaanbaatar city.

19. 2. Starting process producing of CRM of Mongolian people hair
2. Starting process producing of CRM of Mongolian people hair. We are starting collect hair samples from all provinces of Mongolia. For some elemental analysis using INAA. 3. INAA for REE of Mongolian deposites 4. Environmental monitoring around indusrtial and mining areas
