DETERMINATION OF ~(131)I BASED DOSE EQUIVALENTS FOR EMISSIONS OF SHORT-LIVED IODINE ISOTOPES

摘要

The coefficients required for evaluating the inhalation dose from short-live iodine isotopes entering the human body during a radiation accident associated with a spontaneous chain reaction are validated computationally. Such coefficients make it possible to reduce the effect of a collection of iodine isotopes to that of an equivalent amount of ~(131)I. The dose inhalation load from an iodine emission aerosol cloud and the site contamination with ~(131)I are evaluated for a spontaneous chain reaction in systems consisting of enriched metallic uranium with 10~(19) fissions with no localizing facilities present.
