The previous set of basic radiation protection recommendations produced by NCRP was Report No. 116, Radiation Protection Guidance for the United States (1993). Since 1993, substantial advances in radiation effects knowledge, as well as radiation protection understanding and culture, have occurred.
New knowledge has been obtained on radiation effects at doses lower than apparent in 1993. A review of recent radiation epidemiologic studies by NCRP Scientific Committee SC 1-25 will address dose-response models in general, including threshold models, and their applicability to radiation protection guidance. The results of the SC 1-25 effort will be reflected in the Council Committee 1 (CC 1) report.
Noncancer effects such as cardiovascular disease and cataracts are emerging as potentially important concerns. NCRP Scientific Committee SC 1-23 will evaluate recent studies on the radiation dose response for the development of cataracts, also considering the type and severity of the cataracts as well as the dose rate, and; provide guidance on whether existing dose limits to the lens of the eye should be changed in the United States. The results of the SC 1-23 effort will be reflected in the CC 1 report.
In NCRP Report No. 116, discussion of ethical foundations had not been introduced, the medical use of radiation had not been explicitly addressed, and the severity of health outcomes had not been addressed in a context of radiation protection. Key events such as the Fukushima nuclear reactor accident and the ever-rising increase in population exposure to medical use of radiation [e.g., computed tomography examinations, positron emission tomography scans, nuclear medicine procedures] have increased awareness of the importance of radiation protection guidance in the United States.
In 2007, the International Commission on Radiological Protection (ICRP) published an update of their recommendations (Publication 103). Subsequently an ICRP report on tissue reactions (previously called deterministic effects) and noncancer effects was published in 2013 (Publication 118). While the overall goals for radiation protection in the United States are the same as those for the international community, there are some differences in the specific approaches taken to obtain these goals [i.e., in implementing the three pillars of radiation protection of justification, optimization (the as low as reasonably achievable principle), and dose limitation].
The CC 1 Report will point out where there is consistency between current U.S. and international radiation protection guidance and where there are other points of view for issues where the NCRP guidance is different for the United States and the rationale for such differences.
Unique aspects of the manner in which CC 1 will operate include:
- The first Committee formed under the direct oversight of the Council.
- All NCRP Program Area Committees (PACs) will participate in the development and review of the recommendations.
- The 2015 NCRP Annual Meeting was on the topic “Changing Regulations and Radiation Guidance: What Does the Future Hold?” and addressed the rulemaking activities ongoing within U.S. agencies for which the CC 1 guidance should prove useful.
- An extensive effort will be made to consult with and present to numerous national and international stakeholder groups during both the development and review phases of the CC 1 work.
Write a report to update and expand the basic radiation protection recommendations of NCRP Report No. 116, Radiation Protection Guidance for the United States (1993), applicable to current needs in the United States.
