Exposure during the first trimester is the most hazardous. There are special requirements for pregnant women. Laboratory Access Access to the lab is limited to authorized individuals. A record of the training sessions will be kept on file. A security card is required for laboratory access.
Samples Do as much sample preparation as possible before entering the lab.
There is no hood, so use solvents sparingly. Samples may remain in the lab only while you are present. Please take them with you when you leave. If you are working with anything particularly hazardous, let the lab manager and others working in the lab know. There are slight differences in the safety considerations for each of the various radiation sources.
