Abstract:
An optical radiation hazards special study was performed on the AGA Model 4D Geodimeter used by the Field Surveys Division, USATOPOCOM, during February - April 1971. It was found that this device, which is used for the precise measurement of distance, emits an optical beam which is a potential ocular hazard if appropriate safeguards are not employed. It was recommended that personnel not view the direct beam even momentarily within a range of 3 m and that personnel not continuously stare into the beam within 300 m in the finder beam mode or 200 m in the operating beam mode. Precautions relating to the use of a retroreflector at close ranges, directing the laser beam through glass, and the use of binoculars were given. Preplacement and periodic eye examinations for using personnel were also recommended. (Author)
