Abstract
An ideal bactericidal process is one in which a misapplication or an overdose cannot possibly be fatal to the operator or to the consumer of the sterilized product. The new mercury arc lamp radiates in the 2,537 Aå region as well as in the 1,850 Aå region. The longer waves have a strong germicidal effect; and the shorter waves are used in converting atmospheric oxygen into ozone, so that irregular or shaded areas of a surface being radiated are sterilized by ozone. The germicidal efficiency of the new lamp is thus dependent upon the combination of the radiations from the two regions of the spectrum. A special glass for the envelope of the lamp had to be developed. Details of lamp construction are given and typical applications of the lamp in hospitals, air‐conditioning, etc., are appended. Of particular interest is the processing of meat, which is rendered very tender under the action of the lamp.
