The purpose of this publication is to describe how the Commission has relied on ethical values, either intentionally or indirectly, in developing the system of radiological protection with the objective of presenting a coherent view of how ethics is part of this system. In so doing, it helps to clarify the inherent value judgements made in achieving the aim of the radiological protection system as underlined by the Commission in Publication 103. Although primarily addressed to the radiological protection community, this publication is also intended to address authorities, operators, workers, medical professionals, patients, the public, and its representatives (e.g. NGOs) acting in the interest of the protection of people and the environment. This publication provides the key steps concerning the scientific, ethical, and practical evolutions of the system of radiological protection since the first ICRP publication in 1928. It then describes the four core ethical values underpinning the present system: beneficence/non-maleficence, prudence, justice, and dignity. It also discusses how these core ethical values relate to the principles of radiological protection, namely justification, optimisation, and limitation. The publication finally addresses key procedural values that are required for the practical implementation of the system, focusing on accountability, transparency, and inclusiveness. The Commission sees this publication as a founding document to be elaborated further in different situations and circumstances.<br style="font-size: 12px;" /></p> Mon, 26 Feb 2018 15:10:43 +0000 Highly Anticipated Dose Coefficients for Radon Now Available on newly Launched ICRPaedia.org http://www.icrp.org/page.asp?id=375 <p class="MsoNormal"><span style="font-size: 10pt;">Radon, a naturally occurring gas that is found everywhere, is the largest contributor to radiation dose from natural sources world-wide, and the second leading cause of lung cancer after smoking.</span></p> <p class="MsoNormal"><span style="font-size: 10pt;">Given this, it is not surprising that radon has long been an important subject for radiological protection.

Dosimetric models, adopted in Publication 108, provide dose coefficients (DCs) for a group of reference entities [Reference Animals and Plants (RAPs)]. The DCs can be used to evaluate doses and dose rates, and to compare the latter with derived consideration reference levels (DCRLs), which are bands of dose rate where some sort of detrimental effect in a particular RAP may be expected to occur following chronic, long-term radiation exposure, as outlined in Publication 124. These dosimetric models pragmatically assume simple body shapes with uniform composition and density, homogeneous internal contamination, limited sets of idealised sources of external exposure to ionising radiation for aquatic and terrestrial animals and plants, and truncated radioactive decay chains. This pragmatic methodology is further developed and systematically extended in this publication, which supersedes the DC values of Publication 108. Significant methodological changes since Publication 108 include: implementation of a new approach for external exposure of terrestrial animals with an extended set of environmental radioactive sources in soil and in air; considering an extended range of organisms and locations in contaminated terrain; transition to the contemporary radionuclide database of Publication 107; assessment-specific consideration of the contribution of radioactive progeny to DCs of parent radionuclides; and use of generalised allometric relationships in the estimation of biokinetic or metabolic parameter values. These methodological developments result in changes to previously published tables of DCs for RAPs, and revised values are provided in this publication. This publication is complemented by a new software tool, called 'BiotaDC', which enables the calculation of DCs for internal and external exposures of organisms with user-defined masses, shapes, and locations in the environment and for all radionuclides in Publication 107.</span><span style="font-size: 10pt;">&nbsp;</span></p> <h1></h1> Fri, 8 Dec 2017 16:16:54 +0000 Presentations Available for Joint ICRP-RERF-JHPS Workshop http://www.icrp.org/page.asp?id=372 <p>Presenations from the&nbsp;Joint ICRP-RERF-JHPS Workshop on Recent Progress in Radiation Dosimetry for Epidemiology and Radiological Protection can now be found&nbsp;<a href="page.asp?id=370">here</a>&nbsp;on www.icrp.org.</p> <p>This workshop took place on Saturday, December 2nd, 2017 at the University of Tokyo.&nbsp; The outstanding presentations remaining will be uploaded to the above next week.</p> Thu, 7 Dec 2017 19:54:50 +0000 Passing of Main Commission Emeritus Member Charles Meinhold http://www.icrp.org/page.asp?id=371 <p><img style="float: right; border: 1px solid black; margin: 10px;" src="admin/Charles%20Meinhold.jpg" alt="" width="150" height="150" /></p> <p>Charles B.

It was a testament to his breadth of expertise that he was also Chair (1985-1993) of ICRP Committee 2 on secondary limits, and Vice-Chair (1993-2001) of the Main Commission.

The concept was subsequently developed further, and practical guidance was provided in 2001. The DRL has been proven to be an effective tool that aids in optimisation of protection in the medical exposure of patients for diagnostic and interventional procedures. However, with time, it has become evident that additional advice is needed. There are issues related to definitions of the terms used in previous guidance, determination of the values for DRLs, the appropriate interval for reevaluating and updating these values, appropriate use of DRLs in clinical practice, methods for practical application of DRLs, and application of the DRL concept to newer imaging technologies. This publication is intended as a further source of information and guidance on these issues. Some terminology has been clarified. In addition, this publication recommends quantities for use as DRLs for various imaging modalities, and provides information on the use of DRLs for interventional procedures and in paediatric imaging. It suggests modifications in the conduct of DRL surveys that take advantage of automated reporting of radiation-dose-related uantities, and highlights the importance of including information on DRLs in training programmes for healthcare workers. The target audience for this publication is national, regional, and local authorities; professional societies; and facilities that use ionising radiation for medical purposes, and responsible staff within these facilities. A full set of the Commission&rsquo;s recommendations is provided.</span><br style="font-size: 12px;" /><br style="font-size: 12px;" /></p> <h3>Recommended reference format for citations</h3> <p><span style="font-size: 12px;">ICRP, 2017.
