Ultra-Violet Radiations of Fluorescent Lamps

evaluation of ultra violet emissions radiated from compact fluorescent lamps of iranian current brands

background compact fluorescent lamp (cfl) is a developed fluorescent lamp type designed to saving energy. cfls can cause an increased health risk to humans due to the ultraviolet radiation. objectives the current study aimed to assess the ultraviolet radiation emitted from compact fluorescent lamps in highly used iranian brands. materials and methods this experimental study was conducted on 16 ...

Some Common Conditions Treated by Ultra-Violet Radiations

In this paper I have chosen some diseases and conditions which can be greatly benefited by the use of ultra-violet light. In writing these notes I have dealt with each subject from three points of view, viz : (1) the rationale of the use of the ultra-violet rays; (2) the available authoritative literature on the subject; and (3) the technique in detail. The following ten conditions will now be ...

ULTRA-VIOLET RADIATIONS IN CONDITIONS OF EXTREhlE CALCIUM AND PHOSPHORUS DEFIClENCY

Definite research for the causative factors in the nutritional disturbance known as rickets was begun by various observations as to its distribution and occurrence. In 1890 T. A. Palm (1) showed by a geographical survey that lack of sunlight seemed to be one of the chief factors in the causation of rickets. This led to the use of the sun bath in the treatment of rachitic children. In 1914 Rolli...
