The GI-01 irradiator, fitted with one appropriate radionuclide source, can be used as a reference source of a homogeneous collimated gamma beam in the range of tenths of μGy/h up to units of Gy/h. The GI-01L is primarily designed for one Cs-137 source and GI-01H for one Co-60 source. Optional attenuators can be supplied with the irradiator.
