TEST BENCH FOR DETERMINATION OF METROLOGICAL COEFFICIENTS OF EFFECTIVENESS OF INTERNAL PROTECTION OF TYPICAL GAMMA-SPECTROPHOTOMETRIC COMPLEXES

摘要

A test bench for determination of metrological coefficients of effectiveness of internal protection of typical gamma-spectrometric complexes comprises a detector, units of outer upper and outer lower multi-layer protection, dust-protective and heat-insulation screens, elements of fixed volume and composition of air. In the space of the unit of the outer upper protection fixed space in cylindrical form is separated, this surrounds in perimeter the upper part of the detector, and position of the sample.
