All workers accessing the controlled and exclusion areas of the Nuclear Science Laboratory are required to follow the Simon Fraser University’s Radiation Safety dosimetry policy outlined in the Radiation Safety Manual of Policies and Procedures . In addition to the badging requirements found in Appendix H the manual, all workers operating and conducting experiments involving neutrons or the neutron generator are required to wear neutron-measuring dosimeters. Internal dosimetry such as bioassay is currently not available.
The provider for gamma-ray and neutron dosimeters at Simon Fraser University is National Dosimetry Services by (NDS) Health Canada. The InLight Nova OSL Dosimeters are used for gamma-ray dose monitoring while the neutron dose is monitored by the NDS Neutron Dosimeters. Quarterly reports of gamma-ray and neutron dose evaluation from the dosimetry program are received and analyzed by the Simon Fraser University Radiation Safety. The dose received by the workers at the Nuclear Science Laboratory is communicated to the Nuclear Science Laboratory Radiation Safety Officer.
In addition to the requirements for personnel monitoring found in the Radiation Safety Manual of Policies and Procedures , any quarterly radiation dose received by a person working with the neutron generator will be investigated and actions will be taken to restore the effectiveness of the radiation safety program. If a dose has been reported above the threshold limit Radiation Safety Officer of the Nuclear Science Laboratory will investigate the incident jointly with the Radiation Safety Officer of the Simon Fraser University, while the Radiation Safety Officer of the Nuclear Science Laboratory will report the accident to the Canadian Nuclear Safety Commission.
Workers at the Nuclear Science Laboratory will be informed in writing about the yearly dose reported through the dosimetry program. The information will be provided by the Nuclear Science Laboratory Radiation Safety Officer following a submission of the Annual Compliance Report.
Should a worker in the Nuclear Science Laboratory become pregnant, special consideration must be made to ensure limited exposure to the embryo or fetus. Once a worker is aware of their pregnancy they are strongly encouraged to inform in writing the Nuclear Science Laboratory Radiation Safety Officer. Upon disclosure of a pregnancy, the Radiation Safety Officer will provide the following services:
