Patient exposure and radiation risk in Bulgarian diagnostic nuclear medicine. II. Somatically effective dose equivalents to the patients and assessment of risk.
Somatically effective dose equivalents from some frequently employed diagnostic radiopharmaceutical applications in Bulgaria are reported for 1980. Using ICRP risk factors for stochastic somatic effects, the excess number of expected fatal malignancies in the future resulting from this medical radiation source was calculated. This number (approx. 10) is relatively small in comparison with the total number of officially registered malignancies in Bulgaria. A comparison of the traditionally used population doses (e.g. GSD, LSD) in Bulgaria and other countries is also included. It is recommended to reduce the use of 131I-iodide in thyroid in vivo diagnostics in order to lower radiation exposure of patients.
