![]() Other information on practical aspects of personal air sampling and related exposure control efforts are presented in the report. These studies indicate that although breathing-zone activity measurements might provide the best (although not always accurate) means to estimate intake, estimates of uptake and internal dose usually should be made with bioassay or whole body counting. Research concerning the applicability of air-sampling measurements for estimating intake, uptake, and internal dose was also reviewed. The research literature emphasized that estimates of an individual's exposure may be greatly underestimated if based on general area air samples, as is common practice in current licensee programs, due to the unpredictable variability of airborne-activity concentrations in the worksite. However, a one-sample t-test of this data did nd that the overall mean value of the cap lamp/nose ratio was not signicantly different than 1 (p-value 0.21). ![]() The performance tests show that personal air samplers are available which can provide a reliable, convenient means for breathing-zone sampling of workers in practically any work environment which might be encountered in the licensee industries. Personal sampling is a method of sample collection whereby the dust sample collected is in the breathing zone of a mine worker while performing occupational duties during a work shift. dust levels and imprecision of the current personal sampler is a greater inuence than the sampler location within the breathing zone. The recommendations are based on performance tests of currently available samplers, a review of research and regulatory literature, and a survey of current licensee air-sampling programs. Recommended applications for personal air sampling in NRC licensee radiation protection programs are presented. SAMPLE Simply open the sampler at the samplingSimply open the sampler at the sampling site and attach it to the worker in the breathing zone or hang in an areabreathing zone or hang in an area.
