Development of a Standard for the Monitoring and Internal Dosimetry of Exposed Workers of Nuclear Medicine

A new ISO standard is under development to provide guidance for the practical application to the staff involved in the diagnostic or therapeutic use of radionuclides in medicine of the three ISO standards dedicated to internal contamination. It takes into account the special aspects in nuclear medicine resulting from the short effective half-times of the nuclides in use and the distances between department of nuclear medicine and whole body and thyroid counting facilities or laboratories undertaking spectrometry on urine samples. This presentation enhanced two important points addressed in this future standard: the need for a monitoring programme and the design of the different proposed monitoring programmes. (author)
