Radiotoxicity

Definition

Radiotoxicity refers to the harmful effects that radioactive substances can have on biological organisms, particularly through the internal exposure of living tissues to ionizing radiation. The extent of radiotoxicity depends on factors such as the type of radiation emitted, the energy of the radiation, and the biological characteristics of the target tissue. In medical applications, understanding radiotoxicity is crucial for minimizing risks while utilizing radioisotopes for diagnosis and treatment.
