Introduction: As a valuable imaging modality, Nuclear Medicine (NM) indications is raising in clinical practice. The remained portion administrated radioactive material in patients’ tissues is a critical issue, especially when the procedure is performed in hospitalized patients, where the non-radiation workers present. The aim of this study was evaluation the dose of non-radia...

The use of nuclear medicine imaging and CT has grown dramatically over the last several decades. In the Unites States, the annual number of nuclear medicine procedures increased 3-fold (from 7 to 20 million) and the annual number of CT procedures 20fold (from 3 to 60 million) between 1985 and 2005 (1). As a result of this increased medical exposure of the population, the average (i.e., per-capi...

Introduction: Ionizing radiation in medical imaging is one of the dominant sources of exposure, and correct knowledge of radiation protection, affects staff safety behaviors during procedures. This study aimed to assess the radiation protection Knowledge, Attitude and Practice (KAP) amongst nuclear medicine centers' staff in Iran. Methods: To evaluate the...
