Methods for exposure of laboratory animals to ultraviolet radiation

Human Exposure to Filtered Solar Ultraviolet Radiation

The erythemal exposure due to filtered ultraviolet radiation has been evaluated with a dosimetric spectrum evaluator in a glass enclosure to simulate a sun-room with glass roof and walls, in a greenhouse and in a small and large car. The ratio expressed as a percent of the erythemal irradiances to the shoulder of a person in an upright position inside each of the environments to those measured ...

Personnel internal radiation exposure to iodine-125 in a radioiodination laboratory: Exposure levels and trends

ABSTRACT Background: Monitoring internal exposure of individuals handling significant amounts of iodine-125 (I-125) for iodination is of great importance. These individuals are potentially exposed to external contamination, and internal contamination through inhalation, ingestion and intact skin absorption, to I-125. Considering radiological toxicity of this radionuclide its monitoring in the w...

Assessment of ultraviolet radiation exposure of welders working in Shahrud City, Iran, 2014

  Background : Farmers and welders who work in open spaces and are exposed to direct sunlight are often exposed to sunlight radiation o n the neck and head . Thus, they may be afflicted with various types of skin cancer . The aim of the present study was to investigate the amount of UV exposure in welders working in Shahrud City , Iran .   Materials and Method s : This cross-sectio...

Increased exposure of Southern Ocean phytoplankton to ultraviolet radiation

[1] Satellite remote sensing of both surface solar ultraviolet radiation (UVR) and chlorophyll over two decades shows that biologically significant ultraviolet radiation increases began to occur over the Southern Ocean three years before the ozone ‘‘hole’’ was discovered. Beginning in October 1983, the most frequent occurrences of enhanced UVR over phytoplankton-rich waters occurred in the Wedd...
