Report of the CIRRPC (Committee on Interagency Radiation Research and Policy Coordination) Policy Subpanel on SI (International System of Units) Metric Radiation Units

摘要

The Subpanel's recommendation to CIRRPC for U.S. policy concerning the use of SI radiation units is as follows: Recognizing that use of the International System of Units (SI) for radiological quantities is increasing internationally but is not currently widely accepted in the United States, and recognizing that the existing U.S. policy is to plan for the increasing voluntary use of SI units domestically, it is recommended that it be U.S. policy to use dual radiation units in Federal activities. However, it is recognized that in certain operational situations, by reason of economy or safety, the utilization of dual units is undesirable. Therefore, in justified situations, agencies may adopt that system of units which best meets their needs. The objective of the recommended use of dual units is primarily to familiarize people with the SI units. The Subpanel has made suggestions on how the policy should be implemented by Federal agencies. The Subpanel recommends that the policy be reexamined in about five years following an assessment of the use of SI radiation units both internationally and within the United States.
