GI-01L Gamma Irradiator

The GI-01L gamma irradiator, when fitted with appropriate Cs-137 source, serves as a reference source of homogeneous collimated gamma ray beam ranging from some tenths of μGy/h to Gy/h. This type of equipment is normally used in metrology laboratories for the calibration of gamma dose rate and dose meters.

The GI-01L Gamma Irradiator consists of a lead shielded container for one radiation source, a beam collimator, a control unit, and safety and alarm systems. The collimator meets the requirements of ISO 4037-1:2019 standard (Radiological protection — X and gamma reference radiation for calibrating dosemeters and doserate meters and for determining their response as a function of photon energy — Part 1: Radiation characteristics and production methods).

The irradiator and other components in the calibration laboratory can be fully remotely controlled from a host PC.

The shielding of the irradiator is optimized for maximum activity 60 TBq (1600 Ci) of Cs-137.
