Background/aims: The pathogenic role of ultraviolet (UV) in the development of skin cancer, skin ageing and immunosuppression makes it important to monitor human exposure to UV radiation. In a previous study we constructed UVB and UVC dosimeters based on a thermoluminescent phenomenon induced by UV in CaF2:Dy and CaF2 crystals.

DNA can be used to establish and monitor solar UVB dose. Since the principal molecular site of UVB damage in living organisms is DNA, it is logical to quantitate biologically effective solar UVB in DNA dosimeters. In addition to their particular sensitivity to UVB, DNA dosimeters have the advantage of a 2 pi geometry for collecting diffuse UVB ...

An idea to reduce angular dependence of dosimeter having a disk-shaped detection region
, 2020When dose measurement is carried out using an optically stimulated luminescence (OSL) dosimeter which uses a disk-shaped dosimeter in the diagnostic X-ray examination, angular dependence of the dosimeter should be taken into consideration.

The effects of radiation on aqueous solutions of high polymers have been the subject of numerous investigations concerned with explaining basic mechanisms in radiation chemistry and biology. The work of Alexander and Charlesby (1) in England, Durup (2) in France, and Flory (3) in the United States represents almost the entire range of experimentation ...
