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. Meinhold (1934-2017) was among the select few appointed as Emeritus Members of the ICRP Main Commission. This honorary life-long distinction, conferred only by unanimous agreement of the Main Commission, is an expression of appreciation for extraordinary contributions.</p> <p>All who knew Charlie were saddened to learn of his passing on November 3rd, 2017.</p> <p>His work with ICRP began in 1967, contributing to what would become ICRP <em>Publication 15</em> Protection against Ionizing Radiation from External Sources. Soon thereafter, Charlie was a member (1973-1977) of ICRP Committee 3 on external exposure, and then Chair (1977-1985) of ICRP Committee 3 newly renamed 'Protection in medicine'. 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. Upon retirement from this latest position, he was appointed as an Emeritus Member of the Main Commission.</p> <p>Charlie was also on the International Radiation Protection Association Executive Council (1984-1996), serving as Vice-President (1988-1992) and President (1992-1996).</p> <p>In addition to his international work, Charlie was active at home in the US, serving on the National Council on Radiation Protection and Measurements (NCRP) from (1979-2002), and its third President (1991-2002).</p> <p>Charlie will be missed by us all.</p> <p><a href="http://ncrponline.org/wp-content/themes/ncrp/PDFs/Obits/Meinhold_obit.pdf" target="_blank">Please also see the In Memorium message from NCRP</a>.</p> Thu, 23 Nov 2017 00:10:21 +0000 Joint ICRP-RERF-JHPS Workshop Dec 2017 Second Announcement http://www.icrp.org/docs/Joint ICRP-RERF-JHPS Workshop Dec 2017 Second Announcement.pdf http://www.irpa.net/docs/Joint ICRP-RERF-JHPS Workshop Dec 2017 Second Announcement.pdf Thu, 16 Nov 2017 16:27:51 +0000 ICRP-ICNIRP 2017 Meeting Statement http://www.icrp.org/docs/ICRP-ICNIRP 2017 Meeting Statement.pdf http://www.irpa.net/docs/ICRP-ICNIRP 2017 Meeting Statement.pdf Wed, 15 Nov 2017 16:35:24 +0000 Summary of C1 Paris Meeting October 2017 http://www.icrp.org/docs/Summary of C1 Paris meeting October 2017.pdf http://www.irpa.net/docs/Summary of C1 Paris meeting October 2017.pdf Tue, 14 Nov 2017 14:10:50 +0000 Abstracts and Presentations for the ICRP Workshop on Surface Disposal of Radioactive Waste Now Available http://www.icrp.org/page.asp?id=369 <p><span style="font-size: 11.0pt;">The ICRP Workshop on Surface Disposal of Radioactive Waste was successfully held in Fukushima&nbsp;on Monday November 6, 2017.&nbsp; With special thanks to the Nippon Foundation, members of Task Group 97 and Committee 4 were able to attend this workshop and discuss key topics with members of the community.&nbsp;&nbsp;</span></p> <p>For more information, pictures, abstracts, and presentations, please visit the workshops official page <a href="page.asp?id=368">here</a>.</p> Tue, 7 Nov 2017 13:09:01 +0000 Summary of October 2017 C4 Meeting Paris http://www.icrp.org/docs/Summary of October 2017 C4 Meeting Paris.pdf http://www.irpa.net/docs/Summary of October 2017 C4 Meeting Paris.pdf Fri, 3 Nov 2017 14:26:24 +0000 ICRP Publication 135 Now Available on ICRP.org http://www.icrp.org/page.asp?id=367 <h1>Diagnostic Reference Levels in Medical Imaging</h1> <h2>ICRP Publication 135</h2> <p><span style="font-size: 12px;">Ann.

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.
