ABSTRACT A self-shielded gamma irradiator has been designed and produced for analysis of irradiated food on the market and for scientific work to study gamma rays effect on different materials as well Ultraviolet light can be used to inactivate many types of organisms, including viruses, but it is currently known that UV light only works on surfaces or clear liquids such as water. . UV light radiation has been used for many years in pharmaceutical, electronic, and aquaculture industries as a disinfection medium. . radiaton. , through different types of filters. . UV & . Sunblock. Measuring and comparing the level of ultraviolet radiation, through different types of filters.. Objective. The purpose of this activity is to study the level of ultraviolet radiation resulting from the intervention of a sunlight beam through different types of filters, creating a hypothesis and proceeding to test it using the .
