A HDR 1000 PLUS well type ionization chamber, procured from Standard Imaging, USA, and maintained by Medical Physics & Safety Section (MPSS), Bhabha Atomic Research Centre (BARC), India, as a reference well chamber 1 (RWCHI), was traceably calibrated against the primary standard established by Radiological Standards Laboratory (RSL), BARC for 192lr HDR source, in terms of air korma strength (AKS). An indigenously developed well-type ionization chamber, reference well chamber 2 (RWCH2) and electrometer system, fabricated by CD High Tech (CDHT) instruments Private Ltd., Bangalore, India, was in turn calibrated against RWCH1. The CDHT system (i.e. RWCH2 and CDHT electrometer system) was taken to several hospitals, in different regions of the country, to check the calibration status of lg21r HDR sources. The result of this calibration audit work is reported here. |
