| Abstract: | After being irradiated by neutrons in reactor, single crystal silicon was activated in radioactivity and poses danger to workers in the process of being transferred from reactor for storage. According to technical parameters of a silicon irradiation system, the sample activity and surrounding dose level are calculated, with suggestions of how to optimize design and operation given as well. |
