FEATURES

There is an essential increasing of measuring sensitivity due to use of radionuclides concentrating techniques.

There is a possibility of separate determination of 90Sr and 90Y, that allows making measurement of count samples immediately after the radiochemical extraction of 90Sr, without waiting 2 weeks for equilibrium condition.

Express-analysis of counting samples for not-exceeding of permissible levels.
