DEVICE FOR MEASURING THE POWER dose of gamma radiation NUCLEAR POWER PLANTS IN CONDITIONS OF HIGH-hum of cosmic electrons and protons

摘要

Apparatus for power measurement of gamma radiation of nuclear power plant in terms of background interference from high-energy charged particles, comprising a metal housing, a collimator, inside which are placed two parallel silicon plates, the outputs of which are connected to the circuit anticoincidence, characterized in that, in order to increase the energy range of detected gamma rays to 10 MeV, plates of silicon between a screen from a tungsten alloy to absorb secondary electrons produced n When the interaction of gamma rays with a metal case, the collimator.
