In the early years, the routine personal dosimetry at the Nuclear Research CenterNegev was performed by using photographic films. In 1975, the TLD method was introduced. The routine personal dosimetry was performed by using the LiF:Mg, Ti phosphors (G-1 cards), and employing an automatic Harshaw 2271 reader. The heating of the phosphor was performed by a hot finger, and the integral light outpu...
We carried out the study to assess, using field surveys and personal dosimetry, the potential exposure of pharmacists and pharmaceutical assistants to 60 Hz magnetic fields in a medical center of Taiwan. Field surveys were conducted twice in the pharmacy where two workers were randomly selected and solicited to wear personal dosimetry instruments for a full-shift assessment of personal exposure...
Eyeglass lenses are commonly composed of allyl-diglycol carbonate (CR-39), an alpha-particle detecting plastic, thus making such lenses personal radon dosimeters. Samples of such lenses have been etched to reveal that radon and radon progeny alpha tracks can be seen in abundance, and sensitivities have been calibrated in radon chambers as a primary calibration and with a uranium-based source of...
This work is focused on radiation protection in the PET Centre Prague. The personal year dose equivalents of physicians, technologists and lab-technologists in the period 1997-2000 are presented. Dose equivalents are listed for each group as collective, mean and maximum dose equivalents and number of people in the evaluated group. There is an increase in the dose equivalents in 1999 when the PE...
Neutron individual dosimetry is challenging subject in dosimetry field. Thermoluminescent dosimeter (TLD) is one of the types of personal dosimeters that is extremely used to determine the doses of neutron sources. Typically, this type of dosimeter is used in different centers with a variety of applications after calibration with a standard neutron radiation sources. Usually, materials of TL cr...
The present paper deals with the solid state etch-track detectors and their applications to the detection/dosimetry of neutrons, radon, and radon-decay products. Most of the scientists, actively engaged in the late 60’s and in the 70’s for monitoring the occupational neutron-exposure by etch-track detectors, became also involved in the development of personal monitors for the exposure to radon-...
Supported by the European Commission, the EVIDOS project started in November 2001 with the broad goal of evaluating state of the art dosimetry techniques in representative workplaces of the nuclear industry. Seven European institutes joined efforts with end users at nuclear power plants, at fuel processing and reprocessing plants, and at transport and storage facilities. A comprehensive program...
