dosimetri

thumb|Joanna Izewska gives Ambassador Frank Recker and his delegation a tour of the IAEA Dosimetry Laboratory. Radiation dosimetry in the fields of health physics and radiation protection is the measurement, calculation and assessment of the ionizing radiation dose absorbed by an object, usually the human body. This applies both internally, due to ingested or inhaled radioactive substances, or externally due to irradiation by sources of radiation.
