SEB-01-150 Beta Spectrometer

Beta-spectrometer SEB-01-150 is designed for measuring of beta-emission radionuclides in the environmental samples, food samples, water, milk, radioactive solutions, in aerosol filters, in standard beta-radiation samples.
Expert and express control of beta emitted radionuclide in native samples.

PURPOSE
Beta-spectrometer SEB-01-150 is designed for measuring of beta-emission radionuclides in the environmental samples, food samples, water, milk, radioactive solutions, in aerosol filters, in standard beta-radiation samples
Using of radionuclides concentration techniques essentially raises sensitivity of the method.
Separate definition of 90Sr and 90Y is possible. This allows carrying out measurement of count samples at once after radiochemical allocation of 90Sr, not waiting for condition of balance (2 weeks).
Spectrometer is intended for using in radiology laboratories, in food control laboratories, in quality control of food laboratories, at Nuclear Power Plants, in medical institutions, at Sanitary-Epidemiologic Stations, in veterinary laboratories, in geology and other fields.
