Lymphocyte Depletion Rate as a Biomarker of Radiation Dose to Circulating Lymphocytes During Fractionated Partial-Body Radiation Therapy [PDF]

, 2022
PURPOSE: Radiation causes exponential depletion of circulating lymphocyte populations; in turn, radiation-induced lymphopenia is associated with worse survival for many solid tumors, possibly owing to attenuated antitumor immune responses.

Are passive smoking, air pollution and obesity a greater mortality risk than major radiation incidents? [PDF]

, 2007
Background Following a nuclear incident, the communication and perception of radiation risk becomes a (perhaps the) major public health issue. In response to such incidents it is therefore crucial to communicate radiation health risks in the context of ...

Subjective Perception of Radiation Risk [PDF]

Journal of Nuclear Medicine, 2011
Physicians, medical staff, and patients, much like the general population, are becoming increasingly sensitized to the issue of radiation exposure from diagnostic or therapeutic procedures. The attitudes of patients undergoing diagnostic imaging procedures that use ionizing radiation vary widely. Patient perception of radiation dose strongly influences

Reduction of radiation doses to patients and staff during endoscopic retrograde cholangiopancreatography

The Saudi Journal of Gastroenterology, 2011
Background/Aim: Endoscopic retrograde cholangiopancreatography (ERCP) is associated with a considerable radiation exposure for patients and staff. While optimization of the radiation dose is recommended, few studies have been published.

Risk assessment of medical exposure in X-ray examinations of children

Радиационная гигиена, 2017
The use of the effective dose (the concept of which was developed for radiation protection of workers and public) and the nominal risk coefficients, averaged by sex and age, to assess the radiation risks of medical exposure has some significant ...

COPD Imaging on a 3rd Generation Dual-Source CT: Acquisition of Paired Inspiratory-Expiratory Chest Scans at an Overall Reduced Radiation Risk

Diagnostics, 2020
As stated by the Fleischner Society, an additional computed tomography (CT) scan in expiration is beneficial in patients with chronic obstructive pulmonary disease (COPD). It was thus the aim of this study to evaluate the radiation risk of a state-of-the-

Effective doses for common paediatric diagnostic general radiography examinations at a major Australian paediatric hospital and the communication of associated radiation risks

Journal of Medical Radiation Sciences, 2023
Introduction Health professionals in paediatric medical imaging are routinely required to communicate radiation risks to carers and patients. Effective dose alone cannot be used to specify and communicate the radiation risk for an individual as risks are
