Media Advisory: Workshop to Discuss Adopting International System of Units for Radiation Measurement in the U.S.

Despite national and international recommendations to adopt the metric system for radiation measurements, U.S. government agencies with radiation protection responsibilities continue to use conventional units, such as curie, rad, and rem.  This hinders information exchanges, especially during emergencies, between the U.S. and other countries, most of which use System Internationale (SI) units.  

The National Academies of Sciences, Engineering, and Medicine will host a workshop to discuss how the adoption of SI units for radiation protection in the U.S. could improve communications.  The workshop will examine international experiences in transitioning to SI units and discuss possible steps toward adopting their exclusive use in the U.S.




The workshop will be held on Thursday, Sept. 29, from 8:30 a.m. to 5:30 p.m. EDT and Friday, Sept. 30, from 8:30 a.m. to 12:45 p.m. EDT at the National Academy of Sciences building, 2101 Constitution Ave. N.W., Washington, D.C.  Reporters who wish to attend must register in advance with the Office of News and Public Information; tel. 202-334-2138 or e-mail Those who cannot attend in person can watch a live webcast An agenda for the workshop is available here.
