UNLABELLED The number of computed tomography examinations has continuously increased over the last decades and accounts for a major part of the collective radiation dose from medical investigations. For purposes of quality assurance in modern radiology a systematic monitoring and analysis of dose related data from radiological examinations is mandatory. Various ways of collecting dose data are ...

BACKGROUND The Radiation Reduction During Cardiac Catheterization Using Real-Time Monitoring study sought to examine the effect of a radiation detection device that provides real-time operator dose reporting through auditory feedback (Bleeper Sv; Vertec Scientific Ltd; Berkshire, UK) on patient dose and operator exposure during cardiac catheterization. METHODS AND RESULTS Between January 2012...

Concerns regarding radiation exposure and its effects during pregnancy are often quoted as an important barrier preventing many women from pursuing a career in Interventional Cardiology. Finding the true risk of radiation exposure from performing cardiac catheterisation procedures can be challenging and guidelines for pregnancy exposure have been inadequate. The Women in Innovations group of Ca...

by Robert Ouvrard and Fernando Lopez-Lizana l^evelopments commanding global attention over the past decade have elevated interest in issues of nuclear and radiation safety. In various ways, States today are placing greater emphasis on cooperative projects and services designed to establish or strengthen national capabilities for effective radiological protection. At the international level, the...

This paper describes results of the radiation environmental monitoring performed in the Chernobyl Exclusion Zone (ChEZ) during the period following the 1986 Chernobyl Nuclear Power Plant accident. This article presents a brief overview of five comprehensive reports generated under Contract No. DE-AC09-96SR18500 (Washington Savannah River Company LLC, Subcontract No. AC55559N, SOW No. ON8778) an...

Modern radiotherapy techniques try to deliver the radiation dose by steep gradient. Protocols for these complex treatment delivery techniques are important and extremely sensitive to errors in treatment delivery. To minimize such errors, 3D dosimeters were developed as a relative method for improving dose monitoring and delivery. The aim of this study is to analyze the capability and drawbacks ...
