Neutron dosemeters and radiometers check-up installation

Self-protecting installation UPND-1 for checking-up of neutron dosemeters and radiometers is developed for the operative check-up of the working devices by the equivalent field method and the reverse squares one. The installation is supplied by typical collimators for realization of the last method. When using the method of equivalent field the installation with fast neutron source of UBN-8-6 type (2x107nxs-1) allows a check-up of devices in the following ranges for radio-meter 'KRAN-1': fast neutrons 3.5-1.25x104cm-2xs-1 intermediate neutrons 1.9-4.6x103cm-2xs-1 thermal neutrons 1.8-1.7x103cm-2xs-1; for Dose-meter 'KDN-2' with the detecting unit 'BDMN-0.1': 0.16x10-2-1.25 Svxs-1 (0.16-1.25x102 remxc-1). 12 refs.; 3 figs.; 2 tabs
