background: thermoluminescence dosimetry is one of the dosimetry procedures used widely as routine and personal dosimeters. in order to extend this kind of dosimeters, dental tissue has been examined and was found promising as a tld dosimeter. materials and methods : in this study, 70 health teeth were collected. the only criterion, which was considered for selection of the teeth, was the healt...

The Active Tissue Equivalent Dosimeter (ATED) is a low-cost, easy-to-use and compact tissue equivalent proportional counter designed for use aboard spacecraft, satellites, aircraft, unmanned aerial vehicles high-altitude balloons. ATED was rigorously tested at particle accelerator facilities utilizing heavy ions of charge energy similar to Galactic Cosmic Rays (GCRs). Upon completion the ground...

Abstract Three different dosimetry systems were prepared based on diphenyl thiocarbazone (DTH) dye: polymer films made with, poly(vinyl alcohol), DTH liquid dosimeter and gel dosimeter. All the received several gamma doses. The three analyzing by UV–Vis spectrophotometery before after irradiation. effective dose range in linear part of these is between 1–10 kGy, 0.3–2 50–200 Gy. dosimeters reli...

Marathon runners spend considerable time in outdoor training for and participating in marathons. Outdoor runners may experience high solar ultraviolet radiation (UVR) exposure. South Africa, where running is popular, experiences high ambient solar UVR levels that may be associated with adverse health effects. This feasibility study explores the use of personal dosimeters to determine solar UVR ...

Quality-control dosimetry is important to the routine operation of a radiation processing facility. For many applications this dosimetry must be traceable to a national primary standard. After irradiation at an industrial facility, National Institute of Standards and Technology (NIST)-supplied transfer dosimeters are certified by measurement and dose interpolation from the NIST calibration curv...

Both polymer gels and PRESAGE radiochromic solid dosimeter, in conjunction with optical CT scanning system, have been employed to measure 3-D dose distribution. The 3-D dose maps obtained from these systems can provide a useful tool for dose verification on complex treatments such as IMRT, radiosurgery, and RapidArc. These complex treatments present high dose gradient regions in the boundaries ...

-The influence of the irradiation dose on the parameters which control the temperature sensitivity of thick oxide p-MOS ionising radiation dosimeters is investigated. The temperature sensitivity of the threshold voltage, the carrier mobility and the minimum temperature coefficient current appear to be dose-dependent contrary to what is generally considered. The consequences on the dose measurem...
