dose calibrator, an ionization chamber used in nuclear medicine to measure the amount of radioactivity of a radionuclide before injection into a patient. The dose are calculated in mCi or MBq Dose calibrator
An ionization chamber is an instrument constructed to measure the number of ions within a medium. It usually consists of a gas filled enclosure between two conducting electrodes (the anode and cathode). When gas between the electrodes is ionized by any means, such as by gamma rays or other radioactive emission, the ions and dissociated electrons move to the electrodes of the opposite polarity, thus creating an ionization current which may be measured. Ionization chambers are used in nuclear medicine to determine the exact activity of radioactive dose administered to the patients. Such devices are called 'radioisotope dose calibrators'.

Preparation of radiopharmaceuticals for injection involves adherence to regulations on radiation protection as well as to appropriate rules of working under aseptic conditions, which are covered by these guidelines on Good Radiopharmacy Practice (GRPP). The handling of radiopharmaceuticals is potentially hazardous. The level of risk depends in particular upon the types of radiation emitted and the half-lives of the radioactive isotopes. Particular attention must be paid to the prevention of cross-contamination, and to waste disposal. A continuous assessment of the effectiveness of the Quality Assurance system is essential to prove that the procedures applied in the Radiopharmacy Department lead to the expected quality.
