Risø Calorimeters

Calorimeters are used for measurement of dose by irradiation in electron accelerators. Dose is calculated based on the temperature rise and a calibration function that represents the specific heat of the calorimetric body.

The B6001 polystyrene calorimeter is used only in 5 MeV electron accelerators. Its usable dose range is 3.0 to 40 kGy per irradiation cycle.

The B6002 polystyrene calorimeter may be used in 6-10 MeV electron accelerators. Its usable dose range is 3.0 to 40 kGy per irradiation cycle.

The B6004 graphite calorimeter may be used in 6-10 MeV electron accelerators. Its usable dose range is 1.5 to 15 kGy per irradiation cycle.
