Abstract Low-dimensional perovskite materials and their derivatives with excellent optical performance are promising candidates for light-emission applications. Herein, centimeter lead-halide Cs 4 PbBr 6 single crystals (SCs), which have been used radiation detection the indirect conversion method, were synthesized by a facile solution process. The scintillator exhibits bright green emission pe...

Melatonin/IonizingRadiation/Radiobiology/RadioprotectiyelRadiotherapy/RepalrEnzyme. In spite of the fact that radiotherapy is a common and effective tool fOr cancer treatment; the radio sensitivity of normal tissues adjacent to the tumor which are unavoidably exposed to radiation limits therapeutic gain. For the sake of improvement in radiation therapy, radiobiologythe study of the action of io...

Background: Ultraviolet (UV) radiation is divided into three regions: UVA, UVB, and UVC. Both the quality and quantity of solar UV radiation vary with various factors including the elevation of the sun above the horizon, as well as absorption and scattering of UV photons by molecules in the atmosphere, notably ozone and clouds. It is clear that whereas a moderate amount of UV exposure ...
