Chemical Dosimeters

Chemical dosimeters utilize the chemical effects of radiation. In fact, autoradiogra­phy (see Section 14.5.2) also works in this way. In addition, thermoluminescence

detectors are mentioned: they absorb and store the energy of the radiation at room temperature, and then, after heating to 200—300°C, they emit the energy as lumi­nescent (light) photons. The thermoluminenscence detectors are made of calcium sulfate and lithium fluoride doped with dysprosium.
