محاسبه ی آهنگ دز تابش های گسیلیده از سیلندر مدل ۳۰B محتوی ۶UF طبیعی

Dose rate is one of the most important factors that should be considered in handling, stacking and transportation of nuclear materials for the occupational radiation protection and for the people who are exposing to. Uranium hexafluoride is one of the radioactive compounds of uranium which is used in the enrichment industry. UF۶ is kept and transferred in special carbon steel containers. In this study, the absorbed dose of radiations emitted from ۳۰B cylinder containing fully-aged natural UF۶ is simulated by MCNP۴C code and results are compared with the actual data. The absorbed dose rate depends on some factors such as cylinder contents, storage time before and after discharge, radiation energy, geometry, the enrichment percent, etc. The satisfactory consistency between the calculations and measurements confirms that the simulation model can contribute to the dose mapping data around the UF۶ cylinder and can be used for determination of the allowable exposure time and to control absorbed dose rate. This study is performed experimentally at the KALA ELECTRIC Company.
