Future plan

3. Introduction
In Mongolia, at the Nuclear Research Center of National University of Mongolia, we have been using compact electron accelerator (MT-22) for the neutron activation analysis research.
We are developing methodic of activation analysis for mineral resources, construction materials, samples of environmental studies including air pollution, and import products such as foods, medicines are very essential in Mongolia.
Therefore sharing experiences with FNCA member countries is very important for the development of NAA in Mongolia.

4. NAA applications
Potential end-users for NAA in Mongolia are mining companies, environmental monitoring organizations.
NAA has been used to determine gold, copper, silver, arsenic, uranium, rare-earth elements and heavy metals in geological and environmental samples.

5. Capacity Our NAA possibilities are limited by this neutron flux.
The main equipments is an electron cycle accelerator - Microtron MT-22
Parameter
Data
The energy of the accelerated electrons
22 MeV
The average current
16 mА
The density of the flux of gamma rays
γ/сm2×sec
Thermal neutron flux density
n/сm2×sec
Our NAA possibilities are limited by this neutron flux.
We have a policy to obtain a research reactor.

6. Future plan Improve national and international cooperation
Learning from other countries experiences
Develop new methods
Increase the use of NAA:
Environmental pollution control
To study toxic heavy element in environmental and air pollution samples
Food safety
To control imported food products
Health impacts of industry
To determine basic and accompanying elements in export products of copper and coal minerals.

7. Future plan /next year/
To study elements in flour samples of national industry and import

8. Future plan /next year/
Tuul River
Factors which influences in water quality:
Ulaanbaatar's central sewage treatment facility
Air pollution
Soil pollution
Influx of people
Industrial etc

9. Future plan /next year/
To study heavy elements in Tuul river soil and sediment
