From physics to medicine, fundamentalist Leonidas D. Marinelli

Leonidas D. Marinelli is the greatest Italian-born American radiological physicist. Thanks to his efforts, we have an idea of effect radiation on body; in medical practice a unique treatment for thyroid cancer with help radioisotope I 131 has appeared. The article describes detail life path and formation scientist, which deserves special attention from readers, since came success thanks own perseverance work, despite all difficulties obstacles, he received higher education America, found mentor person Dr. Joachino File, whom they later became colleagues, realized their potential, made many discoveries at intersection physics medicine, are relevant this day. Special work paid two significant Marinelli, these Marinelli’s vessels, allow registering gamma-radiation, formula, designed calculate therapeutic activity . We analyzed available materials, selected, highlighted our various stages spheres tried explain essence activities as much possible.
