P32 has a little bit high emission of beta particles. Beta particles are
completely attenuated by small thicknesses of common materials.Therefore, they
do not pose an external source of radiation dose. Even a high energy beta
particle from a P-32 decay event can only penetrate about 8 millimeters of
tissue. Our radiation-sensitive organs are typically at least 12 to 25
millimeters below the skin surface. However, a beta emitter can cause
radiation dose if ingested. So don't worry too much.
And usually there is safe guide book in the lab, where you can find how much
CPM is safe for people. If you look at the Geiger counter, you can read how much
the emission is making. Screaming itself does not mean it is beyond the safe
line for an adault. and also the book will tell you how to deal with the
emergency. :)
Take care!

: Thanks a lot.
