RE: shielding requirements for P-32
Normally, 1.3 cm (0.5 inches) of acrylic is enough for most of the P-32
electrons. Talking of lead and plastic, for 1 mCi, you may simply use the
lead acrylic shielding (again, commercially 0.5 inches) that you normally
found for I-125. And for Bremsstrahlung, don't worry to much with 1 mci of
P-32, the I-125 lead acrylic will do a good job.
For these quantities, we use body and extremity (fingers) dosimeters.
Many good pratical advices in the HHSC Handbook No.9, 1992

Subject: shielding requirements for P-32
What would be the minimum shielding requirements for a scientist working
with 1 mCi of P-32. I heard several suggestions from fellow lab workers but
wanted to know what the professionals suggest. If one should indeed use
lead in addition to the acrylic, how much lead is needed?
Thanks in advance for all your help. It's nice to know that the "general"
public can have access to such important information through servers like
"radsafe".
