摘 要：The KCl:Eu2+ system response to UV-C was investigated by analyzing the optically stimulated luminescence （OSL） and thermo-luminescence （TL） signal produced by ultraviolet light exposure at room temperature. It was found that after UV-C irradiation, OSL was produced on a wide band of visible wavelengths with decay time that varied by several orders of magnitude depending on the Eu2+ aggregation state. In spite of the low intensity of solar UV-C reaching the Earth’s surface in Madrid （40o N, 700 m a.s.l.）, it was possible to measure the UV-C radiation dose at 6:48 solar time by using the TL response of the KCl:Eu2+ system and differentiate it from the ambient beta radia- tion dose.
