METHOD AND DEVICE FOR RADIATION MONITORING OF AGRICULTURAL PRODUCTION Russian patent published in 1994 - IPC

FIELD: measurement technology. SUBSTANCE: detecting and measuring channels are used for monitoring. Spectrometric channel is made on the base of sodium iodate and radiometric channel is based upon scintillation plastics. During process of monitoring and sorting, express registration of gamma-radiation is preliminary carried out in the range of 10-250 keV in the mode of turnstile by means of plastic detector which has thickness of 10×10 cm² and size of sensitive area no less than 10x10 sq. cm. In case if radioactive substance is detected into the objects they are transferred for precision spectrometric analysis. Detectors of the system are placed in protection casing made of tanks filled with radioactively pure water. EFFECT: improved precision of measurement. 2 cl, 1 tbl, 3 dwg
