ABSTRACT
Many epidemiological studies showed increases of cancer risk in humans following radiation exposure. But, these results mainly came from high dose and high rate radiation exposure and the risk related low dose exposure still remains in question. To overcome the problem about statistical power due to limitation of study population, IARC is processing international collaborative study for pooling data analysis. In Korea, reconstructed cohort of NPP workers based on dosimetry records has followed since 1994. Based on this cohort, we introduce epidemiological study about NPP workers in Korea and investigate the exposure level and death cases in NPP workers exposed to protracted low-dose radiation.
Keywords: epidemiological study, NPP workers, low dose radiation exposure
