Exposure and dose modelling in occupational epidemiology.
Complex and dynamic physiologic processes underlie the exposure-response relations that occupational and environmental epidemiologists study. Simple summary measures of exposure such as the average, cumulative exposure, or duration of exposure, can be applied suitably in exposure-response analyses in many instances. However, there are situations where these metrics may not be directly proportio...
متن کاملThe development and regulation of occupational exposure limits in Japan.
The Ministry of Health, Labor and Welfare, on an administrative basis, establishes and supervises the Administrative Concentration Level, which can be viewed as an Occupational Exposure Limit (OEL) legally binding employers to maintain a good working environment. The Japan Society for Occupational Health, on a scientific basis, establishes the Recommended OELs, which can be viewed as a referenc...
متن کاملEvaluation of Radiation Exposure Pattern and Radiation Absorbed Dose Resulting from Occupational Exposure of Anesthesiologists to Ionizing Radiation
Introduction: Little information is available concerning the radiation exposure of anesthesiologists, and no such data have previously been collected in Iran. This prospective study was performed to determine the amount of radiation exposure of anesthesiologists for the purpose of assessing whether or not dangerous levels of radiation exposures were being reached, and to identify factors that c...
متن کامل[Investigation of reduction of exposure dose in digital mammography: relationship between exposure dose and image processing].
In digital mammograms, granularity is an important image property for the detection of microcalcifications and masses. Therefore, we investigated the relationship between the conditions of various exposure doses and the detectability of RMI156 phantom images with and without image processing for the reduction of exposure dose. The images are processed with Gaussian filter and unsharp-masking fi...
متن کاملReduction of exposure in the management of occupational asthma.
PURPOSE OF REVIEW The management of immunologically mediated occupational asthma may be difficult in clinical practice since complete avoidance of exposure to the sensitizing agent is associated with a substantial adverse socio-economic impact. The purpose of this review was to critically analyze the available information on the effectiveness of reducing exposure as an alternative to complete a...
