Beta/Photon dosimeter

Beta/photon dosimeters are used in cases where there is exposure to either beta radiation or mixed fields of beta radiation and photon radiation.

The dosimeters are equipped with three so-called thermoluminescence detectors, each of which is individually calibrated. One of the detectors is used to determine Hp(10), the personal dose equivalent at a depth of 10 mm in soft tissue. This quantity is a good approximation of the effective dose received. The other detectors determine Hp(0.07), the personal dose equivalent at a depth of 0.07 mm. This quantity gives a good indication of the skin dose received.
