GI-01H Gamma Irradiator

The GI-01H gamma irradiator, when fitted with appropriate Co-60 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-01H 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).

Lead attenuators with a maximum attenuation factor of 5,000 may be installed in front of the irradiator. Attenuators are available with:

  • manual control without indication
  • manual control with electronic position indication
  • remote control with electronic position indication

in sets of 3, 4, 6 or 8 attenuators.

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

The shielding of the irradiator can be optimized to the activities inserted into it. Three models are offered as standard for maximum activities of Co-60 ranging from 25 GBq (675 mCi) to 2.5 TBq (67.5 Ci).
