Anotation:
Nuclear medicine operates with open sources od ionizing radiation. Practically, a chemical substance with a radioactive element is applied into human organism. Radioactive atom has the same chemical properties as a stable atom, except its nucleus is unstable, i.e. it undertakes, with some probability, a structural change accompanied by emission of ionizing particles. Nuclear medicine takes advantage of selective accumulation of a particular element/molecule in a particular organ. Radiation emitted by the accumulating area can be either detected and processed for diagnostic imaging or used for radiodestruction of the target tissue. Radioactive iodine, accumulated in thyroid, is used in diagnostics and therapy of thyroid diseases.
