A Permissible Ultraviolet Lamp for Use by Mine Inspectors.
NTIS: PB/269-901 Available for Reference At Bureau Libraries :20 pages
Present indications are that in about 2 to 3 years phosphor tags will be required in commercial explosives. A permissible 254-nm ultraviolet lamp assembly has been developed to permit mine inspectors to detect such phosphor tags and to establish if nonpermissible explosives were used. This new lamp is powered by a miner's cap battery without interference with the normal lighting requirements of the cap lamp battery. It is compact, lightweight, and rugged with very high ultraviolet output.
