During the maintenance period at Korean nuclear power plants, internal exposure of radiation workers occurred by theinhalation of 131I released to the reactor building when primary system was opened. The internal radioactivity of radiation workerscontaminated by 131I was immediately measured using a whole body counter and the whole body counting was performed again after afew days. In this study, the intake estimated from the record history of entrance to radiation control areas and the measurement resultsof air sampling for 131I in those areas, were compared with that from the results of whole body counting. As a result, it was concludedthat the intake estimation using whole body counting and air sampling showed similar results.
