[ 1 ] - محاسبات دز نوترون در حادثه بحرانیت JCO در Tokaimura با کد MCNPX
Recognizing the accident and estimating absorbed doses at the incident time, is one of the requirements for radiation safety. The aim of this paper is designing a model for assessment of nuclear criticality effectiveness in non-reactor units and evaluation of the effect of variation of distances on dose rate and neutron energy spectrum. In this study neutron dose-rate was simulated between 0.5m...
[ 2 ] - بررسی مقدار مولیبدن99 موجود در محلول رادیوداروی تکنسیمm99
The radioisotope Technetium-99m has unique chemical and nuclear properties; which is widely used in the field of nuclear medicine. This isotope has a half-life of 6.04 hours and the emitted gamma ray has energy of 140.5 keV. This radioisotope is not normally found in nature, but is obtained from radioisotope molybdenum99 decay. molybdenum99 has half-life of 66 hours, and 740 keV Gamma-ray....
[ 3 ] - Assessment of atmospheric dispersion from ANPP hypothetical accident based on Fukushima accident by HYSPLIT model
The atmospheric dispersion of Materials is one of the most important ways of spreading contamination of a NPP accident. In this study, the particle paths were calculated by HYSPLIT model (both pressure and AGL form of trajectory) horizontally and vertically at 0 and 1.5 meters above ground level during 15-day periods for 23& 24 November 2006 start times. Then, the releases values of Fukushima a...
