Beta-spectrometer SEB 01-70 is designed for measuring of beta-emission radio-nuclides in the samples of environmental objects, food samples, water, radioactive solutions, in aerosol filters, in standard beta-radiation samples.
Spectrometer is intended for using in radiology laboratories, in Nuclear Power Plants, in medical institutions, in Sanitary-Epidemiologic Stations, in veterinary laboratories, in geology and other fields.

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.
