Appendix III te Annex G
Decontamination Procedures
1.
General,
Radipactive centamination will very probably at some time
during Overetien CASELErender an essential area or piece of equipment
temporarily unuseble. In such a situation, the reduction of such radioactive
contamination may be mandatory to successful accomplishment of the eperation,
Decontamination ef units and personnel shall be accomplished on the site te
reduce the hazard to eperational levels,

Definitions (Ref. NavMed P-1325)
(1)
Operational Clearance implies that radioactive contamination
exists and that special eperating precedures are required. Commander, Task
Greup 7.3 is responsible for authorizing operetional clearences,.
(2) Final Clearence. Following the completion of decontaminetion,
or if a ship has not been contaminated, Commander Task Group 7.3 may authorize final clearance for a particular ship or unit. This shall apply,
also, te final clearance on the decentamination of all forms ef equipment,
instruments, furniture, end personal items. Final clearance shall imply
that the area or ebject concerned has been monitored and found te have ne
peint exceeding 0.015R/24 hr beta plus gamma and no detectable.alpha emitting
isotopes. In the event that a unit ef the task group has some area or
material, at the conclusion ef Operaticn
5 which has net yielded to
decontamination, this unit may be released to its type commander under
operational clearance,
(3)
It sheuld be remembered that radieective fission preducts decay
as time passes, the most rapid decay taking place within the first few hours
after deten-tion, To compute desages, see "Radiolegical Defense", Vol II
PP 223-229.
DNA
2. Reagents. In most of the decontamination operations which might be required of Task Group 7,3, fresh and/or salt water sprayed under pressure
shall be used for gross decontaminatien, Ordinarily, salt water should net
be used on aircraft.,
Other
reagents which are used where water is inappre-
priate er inadeouate“sret; Standard Cleaner, USN C-152, er 147, 5-10% sodium
citrate sclutien er USAF cleaning cempeund Spec, 2001g (gunk), kerosene and
soap powders. Cleaners with an oil carrier are especially suitable fer aircraft decontaminatien.
