Abstract

Applicable to alpha/beta gas proportional counting systems used for the determination of the alpha-ray or beta-ray emission rates of radionuclides in sample counting. It intends to establish standard methods for calibration and use of alpha/beta gas proportional counters, including measurement of their characteristics.
