Synthesis Calculation of Total Exposure Effective Dose to Members of the Public Due to Radioactive Material Release by Nuclear Fission Product

In this paper total Exposure effective dose caused by release of airborne radioactive material due to leakages with an equivalent diameter of 100 mm & more from the primary to the secondary Circuit is investigated. Exposure’s of receptor from passage of Gamma rays radioactive cloud or the so called air submersion & inhalation of radionuclides during this passage time are considered & also exposure from ground shine of radioactive material which deposited on the ground is considered as route’s of exposure. The maximum concentration( χ/Q) is predicted to be 3.3e-5 sec/m3 & happen at a wind velocity of U=1m/ s in the weather class A at a distance of 600m from the stack which is in good agreement with the amount of 3e-5sec/m3 reported in preliminary report on safety assurance(PSAR)for typical VVER1000 Nuclear Power Plant.
