EXCITATION FUNCTIONS FOR (α,xn) REACTIONS ON OSMIUM TARGETS FOR PLATINUM RADIOTRACER PRODUCTION

摘要

The increasing concentration of Pt, Pd and Rh in the environment is mainly due to the release of these elements from the catalytic converters of the motorveicles. This situation makes it necessary to carry out metallotoxicological experiments on both cell cultures and laboratory animals, in order to assess the impact on living organisms after a Long Term and Low Level Exposure (LLE) of these trace elements, whose effects are In most cases unknown. The use of High Specific Activity Radio-Nuclides (USARN) is a powerful tool in studies related to the biokinetics of trace elements and their effects on human health.
