ICRU report 85: Fundamental Quantities and Units for Ionizing Radiation

Published by: International Commission on Radiation Units and Measurements (Journal of the ICRU Volume 11, No. 1, 2011)

ICRU Report 85, dated April 2011, is the second with the title Fundamental Quantities and Units for Ionizing Radiation, the first being ICRU Report 60 published in 1998. It is stated in the preface that: "The development of the present report was prompted by a few criticisms of Report 60, and while basically introducing no new quantities, it does strive for more precisely worded definitions and clarity." The report comprises the following six chapters: 1. Introduction, 2. General Considerations, 3. Radiometry, 4. Interaction Coefficients and Related Quantities, 5. Dosimetry, and 6. Radioactivity. In October 2011, a revised version of this report was published as ICRU Report 85a. The editor explains that this was published to correct "errors in rather important summary tables of SI prefixes, quantities, and units." This would serve as an invaluable publication for those involved in measuring ionizing radiation. A detailed book review by David J. Thomas is published in Radiation Protection Dosimetry (2012), Vol. 150, No.4, pp.550-552.

  Radiological Protection in Cardiology, ICRP Publication 120 Top

Cardiac nuclear medicine, cardiac computed tomography (CT), interventional cardiology procedures, and electrophysiology procedures are increasingly used in medicine and form the major share of patient radiation exposure. Some of the percutaneous coronary interventions and cardiac electrophysiology procedures are associated with high radiation doses. These medical procedures can result in patient skin doses that are high enough to cause radiation injury and an increased risk of cancer.

The commission provided recommendations for radiological protection during fluoroscopically guided interventions in Publication 85, for radiological protection in CT in Publications 87 and 102, and for training in radiological protection in Publication 113. This report is focused specifically on cardiology, and brings together information relevant to cardiology from the commission's published documents. The material and recommendations in the current document have been updated to reflect the most recent recommendations of the commission.

This document provides guidance to assist the cardiologist with justification procedures and optimization of protection in cardiac CT studies, cardiac nuclear medicine studies, and fluoroscopically guided cardiac interventions. It includes discussions of the biological effects of radiation, principles of radiological protection, protection of staff during fluoroscopically guided interventions, radiological protection training, and establishment of a quality assurance program for cardiac imaging and intervention (Source: www.icrp.org).

Radiological protection in pediatric diagnostic and interventional radiology, ICRP publication 121

P-L. Khong, H. Ringertz, V. Donoghue, D. Frush, M. Rehani, K. Appelgate, R. Sanchez

Pediatric patients have a higher average risk of developing cancer compared with adults for a given radiation dose since developing organs and tissues are more sensitive to the effects of radiation. The longer life expectancy in children allows more time for any harmful effects of radiation to manifest. This publication aims to provide guiding principles of radiological protection for referring clinicians and clinical staff performing diagnostic imaging and interventional procedures for pediatric patients.

The document begins with a brief description of the basic concepts of radiological protection, followed by the general aspects of radiological protection, including principles of justification and optimization. One of the unique aspects of pediatric imaging is with regards to the wide range in patient size (and weight), therefore requiring special attention to optimization and modification of equipment, technique, and imaging parameters.

Guidelines and suggestions for radiological protection in specific modalities - radiography and fluoroscopy, interventional radiology, and computed tomography - are subsequently covered in depth. The report concludes with a summary and encouraging the standardization of procedures, and that it may help increase awareness and ultimately improve practices for the benefit of patients (Source: www.icrp.org).
