Abstract

A novel radiation detection instrument using diamond for measurement of high gamma dose rates is introduced. Diamond has many important benefits for high flux measurement compared to other techniques, including high rate measurement and radiation tolerance. Collaborative work with Kyoto University has shown these detectors can be calibrated and used on nuclear sites for characterisation.
Demonstrated at Sellafield, the diamond detector system will be useful inside the FDNPP Primary Containment Vessel (PCV) for mapping high dose rates and protecting robots.
