Set of means for calibration of stationary radiation monitoring equipment without its dismaunting

A set of means ensuring in-service testing of all the channels of stationary equipment of radiation monitoring of a nuclear power facility without disassembly of the equipment is described in brief. The set ensures testing the gamma-channels using 90Sr+90Y β-radiation sources and a group of cylindrical aluminium diaphragms relative to one point of the range with an error equal to +-(10-20)%; testing the neutron channels using PuBe-neutron source (with 104-105 s-1 flux) relative to one point of each subrange with an error equal to +-(6-20%); testing aerosol- and gas channels using a group of 90Sr+90Y β-radiation sources, 239Pu α-radiation and a set of plane diaphragms with an error equal to +-15%
