As part of its functions, the IAEA periodically reviews the status and continued relevance of the safety standards to the needs of its Member States. Recent work is described on the development of standards for the radioactive discharge control including the development of practical guidance for setting discharge limits, the elaboration of a methodology for the radiation protection of non-human...

This work intends to quantify the risk of internal contaminations in the nuclear medicine staff of one hospital in Henan province, China. For this purpose, the criteria proposed by the International Atomic Energy Agency (IAEA) to determine whether it is necessary to conduct internal individual monitoring was applied to all of the 18 nuclear medicine staff members who handled radionuclides. The ...

The subgroup-22 was formed 4 years ago to investigate nuclear data to improve the keff prediction of thermal benchmarks which are significantly underestimated by the most recent nuclear data libraries. This paper summarizes the evaluation work performed at several laboratories [Oak Ridge National Laboratory (ORNL), Los Alamos National Laboratory (LANL), Commissariat a l’énergie atomique de Bruy...

In order to obtain the precise Pu isotope composition of Irish Sea water reference material issued by the International Atomic Energy Agency (IAEA-381), we analyzed the activities of (239)Pu, (240)Pu and the atom ratio of (240)Pu/(239)Pu by a highly sensitive isotope dilution SF-ICP-MS method combined with two-stage chromatographic separation and purification. With a mean chemical yield of 65% ...

During the past years, special emphasis was put on medical preparedness in the event of radiological or nuclear emergencies. Novin Medical Radiation Institute (NMRI) encouraged and supported the national authorities to enhance their cooperation in improving medical response to radiation accident. NMRI in cooperation with International Atomic Energy Agency (IAEA) and Atomic Energy Organization o...
