Operational Qualification (OQ) Of MINTEC-Sinagama After Cobalt-60 Sources Replenishment

Activity on cobalt-60 sources replenishment at MINTec-Sinagama had been held in May 2014 with total strength of gamma as 440,000 Ci. Therefore, operational qualification (OQ) needs to be done in order to ensure that Sinagama plant is operating well and deliver suitable doses to the customer's products. In this work, three dose mapping exercises were carried out to establish dose distributions and dose reproducibility of plant, which are corresponded to the density of irradiator container (tote) and absorbed dose at normal operation. Dosimeters used were ceric cerous produced by SSDL, Malaysian Nuclear Agency and placed on three planes that represent three-dimensional array. They were located at certain intervals throughout the tote. This paper describes the OQ process and a bit touch on replenishment activity. (author)
