Re: Y-90 Medical Use -Reply

[Kenneth Prendergast <KMP@nrc.gov>]

I was aware of the changes to 35.75, however I was not aware that doses of 150 mCi
could be given as an outpatient.  I would appreciate any information on how this is
done.   Additionally, further informaton on the Y-90 for IM Brachytherapy would be
appreciated.  Thanks in advance!

Ken and RadSafe,

I understand that  Y-90 is being evaluated as a source for intravascular
brachytherapy.  Also, Ken, you might want to check out 10 CFR 35.  The patient
release limits changed recently and the 30 mCi or 5 mR/hr @ 1 meter rule no longer
is applicable.

On a separate subject, I would appreciate some information regarding the use of Y-90
as a radiopharmaceutical for diagnostic or theraputic uses.  I am not familiar with its
use in medicine.  I will agree that it has been a considerable time, more that 10 years,
since I was involved in Nuclear Medicine but I still enjoy the subject.  Thanks in
advance.

Usual dislaimers, the comments are mine and not those of the agency.
