LIMITS FOR RADIATION CONTROL AND RELEASE OF AIR FORCE MATERIAL CONTAMINATED WITH FISSION PRODUCTS
Technical Report

OSTI ID:4316059
Personnel working with aircraft and aircraft parts contaminated by mixed fission product debris are exposed to external and internal radiation hazards. Experiments have shown that the external hazard is, in every conceivable case, the limiting hazard for establishing safety precautions. Therefore, a beta-gamma survey of contaminated materials will be sufficient to determine if the material is to be released to an uncontrolled area. The dose rates from a decaying fission product mixture must be evaluated in terms of the age of the mixed fission products lf one is to establish the true magnitude of the hazard. The range of external beta-gamma radiation measurements which will result in an integrated dose to human skin of no more than 1 rem/year for a continuous 166 hr/ wk exposure is 3.6 mrad/hr for materials contaminated with fission products 1 week old or less, to 0.25 mrad/hr for material contaminated with fission product greater than 3 years old.
