BACKGROUND
The Lab was created in 1999. Now its staff is divided into three professional sub-teams specializing in:
- primary sampling and sample record,
- spectrometry and radiochemistry analyses, and
- agro-chemical and zoo-technical analyses.
The laboratory is licensed to perform radiation control-related operations and has a certificate of independence and technical competence after it’s been accredited according to the National Standards of the Republic of Belarus ISO/IEC 17025-2007.
BASIC OBJECTIVES OF RESEARCH
• Measurement of specific activity of 137Cs, 90Sr, 238,239,240Pu, 241Am, and natural radionuclides in environmental samples;
• Determination of total alpha-beta activity in drinking water;
• Measurement of gamma-radiation equivalent dose;
• Determination of surface beta-contamination in environmental objects;
• Determination of concentrations of incorporated gamma-emitting radionuclides in human body;
• Determination of the basic nutrient elements in soil;
• Safety and quality radiation control of food products, feed and agricultural raw materials;
• Determination of ferrocyanide mass fraction in concentrated mixed feedstuffs;
• Development of new experimental procedures and methods of analyses.
LAB EQUIPMENT
The laboratory is well equipped with state-of-the-art sensitive instrumentation from the world’s top manufacturers. Among the lab equipment used for determination of radionuclides in environmental samples are:
- Tennelec and Canberra gamma-spectroscopy systems;
- Low background alpha-beta counters: Canberra 5SE (USA), WPC 9550, PIC (USA);
- Alpha-Analyst Spectroscopy System (USA);
- Progress-Alpha Spectrometer (Russian Federation);
- Home-made dosimetry, spectrometry, radiometry instruments (Belarus).
Macro- and micro-elements are measured in SOLAAR M6 Atomic Absorption Spectrometer (UK).
For express determination of structure and quality (humidity, fat, ashes, raw protein, cellulose, phosphorous, calcium) of green forage, hay, grain, etc. an infra-red analyzer InfraLUM FT-10 (Russian Federation) is used.
