Re: ?TEDE From Skin Exposure

[BFLOOD@SLAC.Stanford.EDU (Bob Flood)]

True. However, the brem from skin contamination will be present but will
deliver a truly trivial deep dose. If fact, if the deep dose from the brem
proved to be a recordable value, say a few mrem or more, it would be
associated with a catastrophic skin dose. Something on the order of "Just
pay the cashier on your way out of court."
