Hi Judy-

Some of our researchers do this on a regular basis. I assume you are
processing the transport area of the tissue. You probably would not want to
process the injection site as it would be too hot. Usually, there is very
little detectable count in the transport area. You need to survey with a
Geiger-Mueller counter. You can also do wipe surveys. You should wear
gloves. And definitely check with the safety officer. You should not handle
the injection site in your lab unless it is a licensed facility and all the
techs have access to radiation safety training and proper equipment.

Good Luck!
