In this study we have characterised the learning curve for percutaneous nephrolithotomy procedures over 301 cases for six years. Different surrogate parameters of clinical expertise have been used, such as dose area product, total procedure time, fluoroscopy time and personal equivalent doses. In addition, two different endourologists have been monitored; one of whom had specific Radiation Protection training (ICRP 85). Eye lens dose was estimated from thermoluminescent dosimeters. Significant differences were observed between both endourologists, especially in the fluoroscopy time...

A drinking water treatment plant in Viimsi, Estonia was monitored over three years for iron, manganese, radium-226, radium-228, and their daughter nuclides in order to determine the efficiency of the treatment process, get an insight of the removal mechanisms and interactions between radium, iron, and manganese, and assess the overall longevity and performance of the technology and possible build-up of NORM from the treatment process. During the study, samples were collected from raw water, first and second stage filtrate, consumer water, backwash water, and filter materials...

We present and discuss the results of a national survey on radon remediation. The main purpose of the survey was the evaluation of the rate of radon remediation in Switzerland and to identify the main reasons for not taking action in cases of high radon levels. Switzerland is strongly affected by the radon problem and extensive efforts have been made to map the radon potential and to investigate the most effective methods to reduce radon levels in different buildings. However, since the radon remediation of buildings has been given over to experts in the private sector and since there is no obligation to report a finished remediation to the authorities, it is difficult for the Federal Office for Public Health (FOPH) to track the activities in this field...

It is well known that the protection from external irradiation produced by beta emitters is simpler than the corresponding shielding of radioactive sources that emit gamma radiation. This is caused by relatively strong absorption (i.e. short range) of electrons in different materials. However, for strong beta sources specific attention should be devoted to the bremsstrahlung radiation induced in the source encapsulation (matrix), especially for emitters with relatively high beta-endpoint energy (1 MeV), that are frequently used in nuclear medicine...

This paper presents validated building shielding factors designed for contemporary US housing-stock under an idealized, yet realistic, exposure scenario from contaminant deposition on the roof and surrounding surfaces. The building shielding factors are intended for use in emergency planning and level three probabilistic risk assessments for a variety of postulated radiological events in which a realistic assessment is necessary to better understand the potential risks for accident mitigation and emergency response planning...

Cone-beam CT (CBCT) scans utilized for image guided radiation therapy (IGRT) procedures have become an essential part of radiotherapy. The aim of this study was to assess organ and effective doses resulting from new CBCT scan protocols (head, thorax, and pelvis) released with a software upgrade of the kV on-board-imager (OBI) system. Influence of the scan parameters that were changed in the new protocols on the patient dose was also investigated. Organ and effective doses for protocols of the new software (V2...

Our purpose in this study was to compare delivered radiation exposure via Computed Tomography Dose Index Volume (CTDIvol) and Dose Length Production (DLP) measurements from computed tomography (CT) examinations performed on scanners with and without image-quality enhancing iterative reconstruction (IR) software. A retrospective analysis was conducted on randomly selected chest, abdomen, and/or pelvis CT examinations from three different scanners from January 1, 2013 to December 31, 2013. CTDIvol and DLP measurements were obtained from two CT scanners with and one CT scanner without IR software...

Estelle Rage, Sylvaine Caër-Lorho, Dominique Laurier
After the extension of the French cohort of uranium miners with the inclusion of workers employed in the Jouac mines, this article seeks to describe the new Jouac cohort and to estimate mortality risks, as well as to quantify their relation to radon exposure in this extended cohort. The Jouac cohort includes 458 miners hired by the Société des Mines de Jouac between 1957 and 2001. As there is no measurement of radon exposure before 1978 were unavailable, only the post-1977 Jouac cohort (n=314) has been included in the French cohort, creating an extended cohort of 5400 French uranium miners followed up from 1946 to 2007...

Richard Wayne Leggett
This paper reviews age-specific biokinetic data for iodine in humans and extends to pre-adult ages the baseline parameter values of the author's previously published model for systemic iodine in adult humans. Compared with the ICRP's current age-specific model for iodine introduced in Publication 56 (1989), the present model provides a more detailed description of the behavior of iodine in the human body; predicts moderately higher doses to the thyroid for short-lived isotopes of iodine; predicts similar doses to the thyroid for isotopes with half-time greater than a few hours; and, for most iodine isotopes, predicts substantially higher doses to salivary glands, stomach wall, liver, and kidneys...

The debate surrounding possible adverse health effects from the civil use of nuclear power under normal operating conditions has been on-going since its introduction. It was particularly intensified by the detection of three leukaemia clusters near nuclear installations, i.e. near the reprocessing plants in Sellafield and Dounreay, UK, and near the Krümmel nuclear power plant, Germany, the last of which commenced between 1990 and 1991 and was first described in 1992; it continued until 2003, and an elevated risk up to 2005 has been reported in the literature...

Radiation-induced injuries to patient skin as a result of fluoroscopy guided interventional procedures are infrequently reported, often misdiagnosed and there is a need to learn lessons from every injury. Methods: This paper describes two cases of radiation induced skin injuries that are, to the best of our knowledge, the first ever reported cases from Bulgaria and possibly from Eastern Europe, and would thus have educational value. Results: The important messages from the skin injuries reported here are: lack of awareness among part of the interventional specialists about the potential for radiation induced skin injury, misdiagnosis after injury happened because of lack of awareness and knowledge among general physicians, dermatologists and surgeons who followed up cases of skin injuries; lack of system to monitor patients with relatively high exposure; important role played by the medical physicist in diagnosing the injury and overall in initiating actions; role of training and informational material displayed in interventional facilities...

GOAL: To estimate and compare the radiation dose associated with coronary computed tomography angiography (CCTA) examinations on two multi-detector CT scanners (MDCT), 64-MDCT and 128-MDCT, in daily practice. METHODS: Scan parameters of 90 patients undergoing retrospective electrocardiographic gating spiral CCTA exam were recorded during a period on a single-source 64-MDCT and a dual-source 128-MDCT, and average scan parameters were derived that were used for dosimetry...
