Dear Radsafers:

The specific gamma ray constant for F-18 in Nostalgic Units is 5.07.  My
reference is Schleien B, Slaback LA, Jr., and Birky BK:  Handbook of Health
Physics and Radiological Health, Third Edition, table p.6-9, 1998, Williams
and Wilkins, Baltimore, MD. (The factor is in S.I. units, but you multiply
by 27,000 to get to Nostalgic Units.)

Ciao, Carol
