Detect rodent presence and contamination in warehouses, storerooms, etc. by using an ultraviolet lamp to search out and fluoresce rodent urine. Dry rodent urine glows a blue-white if fresh to a yellow-white if old when exposed to longwave ultraviolet light. Rodent hair glows blue-white and is easily identified on sacks or intermixed with food grains.
Forgeries of bank notes, standard checks and travellers' checks are mainly printed on inferior bleached paper or photocopied. Forgeries will glow under UV light and bona fides will be completely dull. Many newer credit cards have an invisible imprint on the front. American Express uses "AMEX". If no imprint, the card is a forgery. Alterations of legal documents such as careful erasure or ink eradication and altering paper textures are detectable with UV light.
Authentic U.S. paper currency has embedded stripes which will fluoresce under ultraviolet light as follows: $5 glows blue, $10 glows orange, $20 glows green, $50 glows yellow, and $100 glows red. The $1.00 bill has no stripe.
GEMSTONE and MINERAL INSPECTION
UV Light can react with the chemicals of a mineral specimen and cause it to glow, called fluorescence. Color and intensity of the fluorescence can identifty many materials. Some minerals and gemstones will fluoresce under shortwave UV ligh and not fluoresce under longwave.
