arguable. Knowledge of facility operations, material forms, and past experience will likely play a key

role in development of such criteria.

10.4 TREATMENT PROTOCOLS - HOW TO TREAT

Treatment can be considered to include both skin decontamination to prevent intake and intervention

actions taken to reduce internal dose once an intake has occurred. Skin decontamination protocols

beyond simple washing should be reviewed by appropriate medical authorities to ensure that
