Answer to Question #947 Submitted to "Ask the Experts"Category: Radiation Workers The following question was answered by an expert in the appropriate field: Q
My work is associated with experiments and I often use 32S in the experiments. I plan to get pregnant this year—will the radiation affect the embryo?
A
Sulfur-32 is a stable isotope of sulfur and is therefore not radioactive. Sulfur-35 is the most commonly used radioactive isotope of sulfur and I assume that is what you are referring to. Sulfur-35 emits a weak beta particle. Accordingly, 35S may pose a health risk (depending on the activity involved) if there is skin contamination or if 35S is ingested/inhaled/injected. For most experimental procedures, 35S poses no risk if handled properly. You are advised to carefully review experimental procedures in order to reduce the possibility of contamination.
If you are planning to become pregnant you should inform your employer in accordance with any institutional policies/procedures. If you elect to continue to work with radioactive material while pregnant you should inform your physician of this fact. Kenneth L. Mossman Professor of Health Physics Director, Office of Radiation Safety
