Quantifying Isotope Activities Using a Gamma Spectrometer Survey Meter
During the operation of high energy accelerators, activated materials are commonly created. The activity and isotopes present in these materials must be characterised for their clearance and release from the facility, or to ascertain their duration of stay in a radiological storage area. An activity estimate method using a gamma spectrum collecting survey meter is […]
Lessons Learned in Change Management for CLS’s Medical Isotope Production Facility
The Canadian Light Source (CLS) holds a CNSC Class II Licence for a 40kW, 35MeV linear accelerator used to produce medical isotopes. CLS maintains the radiation protection program associated with the licence and oversees operation of the facility by a contractor. This presentation will discuss the change management, safety challenges and recent events relating to […]
Implementation of an economical waste monitor for quantification of gamma emitting radionuclides in university research waste streams
In recent years, the nature of the radioactive waste at the University of Saskatchewan (USask) has changed to include more novel accelerator produced isotopes, longer lived contaminants, and isotopes with very restrictive disposal limits such as Ac-227. Existing methods of conservative estimation and generous decay times had become impractical, as overestimating the concentrations could lead […]
