متن کاملEffects of Gamma Irradiation on Proliferation and IL-5 Production of Peripheral Blood Lymphocytes
Gamma irradiation is routinely used for suppression of lymphocyte function in transfusion and transplantation procedures. In recent years, some investigators focused on the effects of ionizing radiation on special aspects of lymphocyte function and considered the possibility of its clinical application for treatment of some immunological disorders. In this study, we evaluated the effects of fiv...
متن کاملTITLE: Air Kerma Primary Standard: Experimental and Simulation Studies on Cs-137
The primary standard for air kerma for the gamma radiation of Cs-137, of the Metrological Laboratory of Ionising Radiation (LMRI), is an ionisation chamber of the type CC01. This instrument was, for the first time, used to characterize the radiation field, in terms of air kerma, produced by a Cs-137 source in an irradiator Shepherd model 81, used mainly for radiation protection calibration purp...
