Abstract:
Dose rate measurements are analysed as being early indicators of the
range of avertable doses in the event of a nuclear accident. The extent to which dose
rates and avertable doses are correlated is evaluated in a Monte Carlo study, using
two years of cumulated meteorological data. The study is carried out for three different
release scenarios from a nuclear power plant, and the avertable doses and
dose rates are obtained in an atmospheric dispersion model calculation. It is shown
that dose rate measurements carried out in the early phases after an accident may
provide a valuable tool for decision support, and action levels of dose rates may be
defined for the purpose of assisting a rapid emergency response.
