The use of activated-charcoal iodine monitors during and following a release of fission product iodines
The system of iodine monitoring in use at BNL has proved to be a satisfactory means of measuring the release of I/sup 131/ to the environment under emergency conditions. Although the cooling air effluent is monitored by other means, which indicated that something had been released, only the system using activated charcoal traps and gamma spectrum analysis could reliably indicate that a release of equilibrium fission product iodines had occurred and accurately measure the amount released. Other media tested by BNL and others do not have as consistently high collection efficiency as the charcoal traps. The system was also useful in locating the defective fuel elements and in explaining the behavior of iodine within the reactors structure. (auth)
