P-32 Chromic phosphate therapies

["Dale E. Boyce" <dale@radpro.uchicago.edu>]

The use of P-32 chromic phosphate for intraperitoneal
treatment of ovarian cancer has increased here.  In the
past, one or two patients a year were treated.  Our
hospital is trying to determine if post surgical treatment
will assist in getting a cure.  In the past it was used
for paliative treatment of metastatic disease.

We had always operated under the assumption that the
insoluble colloid was not excreted.  Yesterday, out of
curiousity, one of our medical physicist acquired a urine
sample from a patient, which we found to contain about
10 nCi/ml of P-32.

Question, has anyone out there been prepping and decontaminating
P-32 rooms?  Have you had any contamination problems?
We are going to check the next few patients more carefully,
but wonder what the body of knowledge has to say wrt. P-32.
