Study on the characteristics of indigenously developed 106Ru/106Rh source

• Indigenous development of 106Ru/106Rh source for QA in personnel monitoring.
• Source parameters such as activity of the source, gamma spectrum were studied.
• Dosimetric parameters such as beam uniformity, BSF, gamma and beta contribution and PDD were studied.
• TLDs, EBT radiochromic film, HPGe and electronic pocket dosimeter were used in the study.

A pilot study was initiated to investigate the characteristics of 106Ru/106Rh source for the purpose of inducting it in Quality Assurance programme of personnel monitoring by Bhabha Atomic Research Centre. Towards this goal, a prototype 106Ru/106Rh source was fabricated indigenously. Different parameters such as activity, gamma ray spectrum, beam uniformity, percentage depth dose, output of the source, contribution of gamma and beta components of the source were studied. The detectors used in the study are CaSO4:Dy Teflon disc, pocket dosimeter, HPGe detector and radiochromic films.
