Low-dose radiation research and radiation protection policy implementation at the Department of Energy
One of the Department of Energy ’s (DOE) highest priorities is the protection of workers, the public and the environment from the conduct of DOE activities. As a self-regulating agency, DOE develops radiation protection policies and orders that integrate national and international consensus standards into requirements that enable it to complete its diverse missions safely and effectively. DOE leadership is unequivocally committed to the well-being of its workforce involved in carrying out its mission. This commitment helps the Department identify and implement viable, safe, and cost-effective methods to protect its...

Radiation epidemiology and health effects following low-level radiation exposure
Radiation epidemiology is the study of human disease following radiation exposure to populations. Epidemiologic studies of radiation-exposed populations have been conducted for nearly 100 years, starting with the radium dial painters in the 1920s and most recently with large-scale studies of radiation workers. As radiation epidemiology has become increasingly sophisticated it is used for setting radiation protection standards as well as to guide the compensation programmes in place for nuclear weapons workers, nuclear weapons test participants, and other occupationally exposed workers in the United States and elsewhe...

Assessment of radioactive cesium deposition using ground-based gamma-ray spectrometry with a LaBr 3 (Ce) detector
Ground-based gamma-ray spectrometry using a LaBr 3 (Ce) detector was conducted to assess radioactive cesium deposition in soil contaminated by the accident at the Fukushima Daiichi Nuclear Power Plant (FDNPP) in Japan. Five sites, including a reference site with relatively low contamination, were selected as having different levels of ambient dose rate due to significant effects of radioactive fallout of 134 Cs and 137 Cs. According to ICRU Report 53, the radioactivity in the ground and dose rate at 1 m above the ground were determined from the measured net count rates of gamma-rays induced from radioactive cesium. B...

EURADOS education and training activities
This paper provides a summary of the Education and Training (E&T) activities that have been developed and organised by the European Radiation Dosimetry Group (EURADOS) in recent years and in the case of Training Courses over the last decade. These E&T actions include short duration Training Courses on well-established topics organised within the activity of EURADOS Working Groups (WGs), or one-day events integrated in the EURADOS Annual Meeting (workshops, winter schools, the intercomparison participants ’ sessions and the learning network, among others). Moreover, EURADOS has recently established a Young Scientist...

Development of a novel artifact-free eye shield based on silicon rubber-lead composition in the CT examination of the head
The aim of this work was to develop a novel artifact-free eye shield and evaluate its effect on the dose received by the eye lens and the resulting image quality in the CT examination of the head. A new material for an eye shield was synthesised from silicon rubber (SR) and lead (Pb) using a simple method. The percentage of Pb was varied from 0 to 5% wt. An anthropomorphic head phantom was scanned with and without the SR-Pb eye shield, and compared with a tungsten paper (WP) eye shield. The distance from the eye shield and head was varied from 0 to 5 cm. The dose to the eye lens was measured using photo-luminescence ...

Organ-specific dose coefficients derived from Monte Carlo simulations for historical (1930s to 1960s) fluoroscopic and radiographic examinations of tuberculosis patients
This work provides dose coefficients necessary to reconstruct doses used in epidemiological studies of tuberculosis patients treated from the 1930s through the 1960s, who were exposed to diagnostic imaging while undergoing treatment. We made use of averaged imaging parameters from measurement data, physician interviews, and available literature of the Canadian Fluoroscopy Cohort Study and, on occasion, from a similar study of tuberculosis patients from Massachusetts, United States, treated between 1925 and 1954. We used computational phantoms of the human anatomy and Monte Carlo radiation transport methods to compute...

NCRP Report no.180 —management of exposure to ionizing radiation: NCRP radiation protection guidance for the United States
NCRP Report No. 180, ‘Management of Exposure to Ionizing Radiation: Radiation Protection Guidance for the United States (2018) ’ was developed by Council Committee 1. The report builds and expands upon previous recommendations of NCRP and ICRP, covering exposure to radiation and radioactive materials for five exposure categories: occupational, public, medical, emergency workers, and nonhuman biota. Actions to add, increase, reduce or remove a source of exposure to humans require justification. Optimisation of protection universally applies, taking into account societal, economic, and environmental factors; addres...

The usefulness of large sample size patient dose audits for optimisation of CT automatic exposure control (AEC) settings
The aim of this study was to demonstrate the usefulness of large sample size patient dose audits for optimisation of CT automatic exposure control (AEC) settings, even when the investigation is limited to only three scanners at a single institution. Pre-optimisation patient dose audits of common CT examinations ( n  > 200 for each protocol) on three CT scanners (two Philips Brilliance and one Toshiba Aquilion) using radiology information system (RIS) data were conducted showing sub-optimal CT AEC performance on the Toshiba scanner. Based on these results, an optimisation exercise was carried out on the non-optimall...

Source term calculation and validation for 18 F-production with a cyclotron for medical applications at HZDR
In this document we present the calculation and experimental validation of a source term for 18 F-production with a cyclotron for medical applications operating at 18 MeV proton energy and 30 μ A proton current. The Monte Carlo codes MCNP6 and FLUKA were used for the calculation of the source term. In addition, the radiation field around the 18 O-enriched water target was simulated with the two codes. To validate the radiation field obtained in the simulation, an experimental program has been started using activation samples which are placed close to the water target during an 18 F-production run of the cyclotron. A...
