Study Protocol for radiation exposure and cancer risk assessment- The Taiwan Nuclear Power Plants and Epidemiology Cohort Study (TNPECS).

TNPECS provides a valuable platform for research and opens unique possibilities for testing whether radiation exposure since the start of operations of nuclear reactors will affect health across the life course. The release of radioactive nuclear species caused by the operation of NPPs caused residents to have an effective dose between 10-7 and 10-3 mSv / year. The mean of cumulative medical radiation exposure dose between the residence-nearest NPP group and the control group is not different (7.69±18.39 mSv and 7.61±19.17 mSv, p=0.114).
