AIR KERMA RATE MEASUREMENT FOR I-125 MEDICAL MICROSOURCES
Measurement procedure of air kerma rate at the reference distance for 125I medical microsources is de- scribed. Expanded uncertainty (k=2) is 3.6 % for the results of measurement with ionization chamber,4.8 % for the results of measurement with scintillation detector and 2.9 % for the combined results re- ceived using both detectors.
