Answer to Question #3255 Submitted to "Ask the Experts"

Category: Suntanning

The following question was answered by an expert in the appropriate field:

I have been looking for a bench shield (not facial shield) to block the UVB (ultraviolet B) radiation from the nucleic acid transilluminator for some time. The closest I came to finding something are some radiation shields for ³²P, beta, or gamma radiation. Would these shields works? If not, do you have any recommendation on where I can find such shields.

The plastic shields for ³²P protection would work very well with UV. Most plastics stop UV, as does most glass. It takes special plastics or pure quartz to allow UV to pass through unattenuated. A one-eighth inch sheet of polycarbonate would provide an optical density of about 10 and would work well as a UV shield. It's a good idea to ask your local health physicist or other safety professional to stop in with a UV meter and test whatever setup you finally decide on.
