Analysis of a Lead Vest Dose Reduction Effect for the Radiation Field at Major Working Places during Refueling Outage of Korean PWR Nuclear Power Plants
Kim, Jeong-In;Lee, Byoung-Il;Lim, Young-Khi;
ABSTRACT
The gamma energy distributions at the major working places during refueling outage of Korean PWR nuclear power plants were measured. In order to estimate the dose reduction effect of a lead vest, Monte Carlo calculation method was used. For the simulations, the MIRD-V phantom with a lead vest was formed and exposed to the measured radiation field. The average measured gamma energy is lower than that of standard which is generally applied to radiation protection procedures. For the efficient use of a lead vest and achievement of radiation protection purpose, it is necessary to estimate the energy distribution of radiation field at working places.
