• Description:
  A study was made of the usefulness of ultraviolet personal dosimeters in efforts to better protect the worker from nonmelanoma skin cancers. Attempts were made to develop an electronic ultraviolet-B dosimeter for the purpose of determining sun exposure from recreational travels and occupational sun exposures. The device developed works by employing a magnesium-tungstate fluor beneath a filter that allows passage of ultraviolet-B (UVB) rays. The fluor responded to the radiation by emitting a photon of light which was recorded on a photo cell and then through a electric circuitry where a digitized recording was made so that the unit read out in a digital manner. The prototype was 4.7 centimeters by 1.5 centimeters and weighed about 2 ounces. The peak wave length of response on all six units tested was about 300, in the middle of the UVB range. Readings taken over 1/10 solar constant up to 2 solar constants were fairly linear in nature. Field tests made to detect radiation penetrating clothing demonstrated that about 8 percent of the incident ultraviolet light passes through a white cotton T- shirt. In determining radiation reaching various sites on the body, units were put on the top of the head on a hat and also hung from a belt at waist level. The reading from the belt level was 18 percent of that on the hat, supporting the notion of direct incident light being a higher radiation level than the light striking the side of the body. Additional testing was planned for a photographic film dosimeter and a commercial dosimeter. The commercial dosimeter was currently available and based on a photochromatic reaction.
