Manufacturer: Theratronics, Canada
- Source: 60Co, fitted with a collimator to provide rectangular fields of up to 35cm x 35cm at 80cm source-to-surface-distance (SSD)
- Beam can be set up at any angle in a plane down the long axis of the 6m x 10m x 4m irradiation cell
- The temperature can be kept constant to better than 0.1°C in the range +15°C to +30°C
- Irradiations are controlled from a control room adjacent to the irradiation cell
- Both rooms are electrically screened from external radio frequency interference and communication between the equipment-under-test and its controller can be achieved using cables passing through 10cm diameter ducts in the radiation shielding
- Equipment for irradiation is mounted on a carriage system allowing test items to be moved in three dimensions to a precision that is a fraction of a millimetre. The carriage is mounted on 6m long rails enabling movement along the long axis of the irradiation room
- The cobalt head has high level of shielding and is loaded with a 300TBq (8.1kCi) source
- Dose rate to water is up to 1.0Gy min-1 at 80cm from the source (March 2011)
