Gamma Calibration Phantoms

Gamma calibration phantoms are used for performing in-situ batch calibration of dosimeters in gamma irradiation facilities.
These phantoms have been designed and built to provide a consistent method of presenting dosimeters to a radiation source as
detailed in ISO/ASTM 51261. Also reference NPL Report CIRM 29 – Guidelines for the Calibration of Dosimeters for Use in
Radiation Processing.
