BACKGROUND The accurate results of the individual doses in personal dosimety which are reported by the service providers in personal dosimetry are very important. There are national / international criteria for acceptable dosimetry system performance. Objective : In this research, the sources of uncertainties are identified, measured and calculated in a personal dosimetry system by TLD. METHO...

Exposure to natural sunlight, specifically solar ultraviolet (UV) radiation contributes to lifetime risks of skin cancer, eye disease, and diseases associated with vitamin D insufficiency. Improved knowledge of personal sun exposure patterns can inform public health policy; and help target high-risk population groups. Subsequently, an extensive number of studies have been conducted to measure p...

background: different kinds and models of personal dosimeters are used in individual monitoring by workers.  performance testing as part of approval procedures is carried out to demonstrate that the essential performance specifications are routinely maintained. there are four service providers in iran which use different luminescence techniques (i. e. tld and rpl) with various kinds of dosimete...

The appropriate evaluation of measured doses in mixed fi elds requires the calibration of dosimeters in relation to different types of radiation and exposure conditions in order to split the signal into individual components corresponding to the specifi c radiation and exposure conditions of the entire period and evaluate the critical level, lower limit of detection and corresponding uncertaint...
