The MPL’s listed herein are to be regardedas advisorylimits for controlunder average conditions. All rsx!ingsof surface contaminationare to be made with Geiger Cour.~ers, with tube walls not substantiallyin excese of 30 mg/cmk with shield open unless otherwiee specified. The surfaceof the probe shouldbe held one inch to two inches from the surfacethat is under observationunless otherwisespecified. For operationalpurposes the contaminatim NPLts presentedbelow will not be considered applicableto spotty contaminationprovidedsuch areas can be effectivelyisolatedfrom personnel: a.
