Electromagnetic radiation is widely used in medicine for both diagnosis and therapy. Its use in therapy assumes the existence of deleterious biological effects which are carefully selected to cause damage where it is necessary (e.g. cancer cells) and to protect the remaining organism. In diagnosis the possible damage caused by radiation is minimized and can be safely used for both patients and health professionals. Taking into account this dichotomy of good and evil the main characteristics of radiation and its use in the clinic are presented.

Palavras-chave : Electromagnetic radiation; biological effect; radiation applications in medicine.
