This standard specifies the absolute measurement with a large-area 2π multi-wire gas flow proportional counter tube. The principle, device, method and data processing of emissivity, etc. This standard applies to α-plane sources with an area not greater than 170mm×120mm and an α-particle emission rate in the range of 1×10s-1~1×104s-1(2πSr) .
