[ RadSafe ] New average annual medical dose

Tue Aug 14 10:20:25 CDT 2007

Hi Wes,

The new estimate is 320 mrem/yr.  This was presented by Fred Mettler at the NCRP April Annual meeting.  This will be in an update of the NCRP 93 report (1987) in which medical exposure is estimated to be 54 mrem/r.

I've seen a ref to a later presentation by Dr. Mettler also, but I forget where.

Regards, Jim
