Re: Re[2]: Emergency Doses Allowed

Planned Special Exposures can not be used for emergencies, since a Planned 
Special Exposure, by definition, is a "planned" and pre-defined occurrence, 
based on a well-documented Action Plan (all defined in 10CFR20.2106). 
However, any dose that exceeds the occupational limits that are due to an 
emergency are required to be subtracted from the PSE bank of potential 
exposure.

Regulatory Guide 8.35 also states the following:

Exposures in excess of the routine occupational dose limits received during 
accident or emergency situations that require immediate action to save human 
lives or to prevent the failure of equipment important to safety are not PSEs. 
However, if conditions associated with an accident or emergency permit 
complying with the conditions specified in 10 CFR 20.1206(a) through (e), a 
PSE can be used. However, all exposures in excess of the routine 
occupational dose limits received during accident or emergency situations 
must be determined and subtracted from the annual 5-rem PSE limit and the 
25 rems allowed for lifetime PSEs (see 10CFR20.1206(e).
