DEVICE TO MEASURE INTENSITY OF DOSE OF GAMMA-RADIATION OF NUCLEAR POWER PLANT UNDER CONDITIONS OF BACKGROUND NOISE FROM HIGH-ENERGY SPACE ELECTRONS AND PROTONS Russian patent published in 2014 - IPC G01T1/02 G01T1/24 

FIELD: power engineering.

SUBSTANCE: device for measurement of intensity of a dose of gamma-radiation of a nuclear power plant under conditions of a background noise from high-energy charged particles comprises a metal body-collimator, inside of which there are two parallel silicon plates, the outlets of which are connected to a circuit of anticoincidence, at the same time with the purpose to expand the energy range of recorded gamma-quanta to 10 MeV between plates of the silicon there is a filter from tungsten alloy for absorption of secondary electrons arising during interaction of gamma-quanta with the metal body-collimator.

EFFECT: expanded energy range of recorded gamma-quanta to energies specified for radiation of a nuclear power plant.
