This standard covers the technique for the quantification of the activity of identified radionuclides using any of a variety of ionization chambers currently available for this purpose. Application of the standard is limited to instruments that incorporate well-type ionization chambers as detectors.
This standard provides a method for obtaining measurements that are accurate to within ± 10% and reproducible to within ± 5% [usually for sources of more than 100 μCi (3.7 × 106 Bq)]. The standard is also intended to assure continuing performance of the apparatus within these specifications. For purposes of this standard, accuracy and reproducibility are described in 4.6.
