HOW MUCH UVB CAN BE EMITTED BY AN INDOOR TANNING LAMP?
There is no regulatory limitation on the amount of UVB which can be emitted by an indoor tanning lamp. However, there is a limit on the maximum amount of minimal erythemal doses. Manufacturers of lamps must submit all operational emission data to the Food and Drug Administration, but this agency does not specify which spectral ratios are acceptable. The current types of lamps and their respec- tive spectral emissions are determined more by customer demand and market considerations than by government regulations. The FDAs concern with spectral output is that the dosage be limited to that amount which induces pigmentation production while avoiding overexposure.
