[en] To evaluate the potential deleterious effects of medically useful radioactive materials,
the radiation absorbed by the patient during the procedure must be estimated. The quantity …

Secondary radiation exposure of patients undergoing radiation therapy with light ions is of
great concern due to possible tissue damage and risk of induction of secondary cancers …

The testis is a radiosensitive tissue. It contains a large number of lobules, which in turn are
composed of convoluted seminiferous tubules. The epithelium inside each tubule consists of …
