摘要：

A number of secondary standards for the absorbed dose rate of beta radiation have been examined to ascertain whether the exchange of beam flattening filters, jigs or beta sources requires a recalibration. In 56 of 57 exchanges the respective absorbed dose rates at the calibration distance differed by less than 1% if the different activities of the exchanged beta sources were taken into account. The relative changes observed were even less than 0. 5% in 80% of all cases.
