IG-13 Gamma Irradiator
A radionuclide irradiator, a source of a homogenous collimated beam of gamma radiation, suitable for SSDL laboratories
The IG-13 gamma irradiator fitted with appropriate radionuclide sources serves as a reference source of homogeneous collimated gamma-ray beam ranging from some tenths of μGy/hr to 1 Gy/hr. This type of equipment is normally used in metrology laboratories for the calibration of ambient gamma dose rate monitors and personal dosimeters.
IG-13 consists of a rotary carousel for up to three sources, and has lead shielding, a beam collimator, a mechanical source position indicator, a control unit and a safety and alarm system. The adjustable feet of the irradiator allow height adjustment of the collimated beam.
