Outpatient (Na)I-131 Therapies

[Chris Alston <alstonc@odrge.odr.georgetown.edu>]

Folks

You might be interested in an article in the J Nucl Med of  this November 
(Vol 41 No 11, 1868 - 1875):
Coover LR, Silberstein EB, Kuhn PJ, and Graves, MW.  Therapeutic I131 in 
Outpatients: A Simplified Method Conforming to the Code of Federal 
Regulations, Title 10, Part 35.75.

I haven't done more than scan it, as yet, but it looks quite useful.  I do 
note that it seems to rely entirely on calculated exposure rates, i.e., 
those estimated using the exposure rate constant for I131, with no 
allowance for patient self-absorption, rather than measured exposure 
rates.  Also, the paper solely addresses the issue of external exposures of 
others, by the patient, and not the question of whether it's sensible, from 
the risk management POV, to release a patient without allowing a few 
half-times for stomach clearance.

P.S.  I offered to send one of the Medphysers some pages from ICRP 54.  Now 
my email archives have been trashed (yes, Virginia, no backup), so I've 
lost her address.  If she'd care to send it to me again, I promise to use 
it, before another calamity occurs.
