A method for exploiting human's internal contamination data for radioactive
release estimation in nuclear power plant accidents is proposed.
Nevertheless, such data is often very rough and uncertain; it is accessible
even in toughest situations when most of the active and passive monitors are
damaged by the accident. These data can be used in combination with other
collectable data for estimating the event scale in severe nuclear power plan
accidents. The rationale behind the method is that nuclear power plant
accidents are often associated with internal contamination of radiation
workers involved in the early stages of emergency response activities mainly
due to the release of 131I in atmosphere. The proposed inverse analytical
approach uses the 131I intake of contaminated workers, their working
conditions, chronology of events, and applied personal safety measures during
the first hours or days of the emergency response activities to estimate the
magnitude of 131I concentration in the air.
