If you recognize this symbol, chances are you might have experience in the medical or scientific fields as a researcher, doctor, nurse, radiation therapist, lab technician, or patient. I've engraved the symbol on thick transparent acrylic which comes in several colors. Thick acrylic is harder to break than the thinner kind. The keychain is finished with a strong stainless steel key ring.
