Adopting the International System of Units for Radiation Measurements in the United States: A WorkshopNuclear and Radiation Studies Board
National Academy of Sciences Building
2101 Constitution Ave NW Washington DC 20418
U.S. Government agencies with radiation protection responsibilities continue to use conventional units for radiation measurements despite 30-year-old national and international recommendations to use SI (System Internationale) units. The use of conventional units hinders information exchanges and communications between the United States and other countries, most of which use SI units, especially during emergencies. For example, U.S. personnel deployed in Japan during the 2011 Fukushima nuclear accident encountered difficulties in communicating with Japanese counterparts and the international radiation protection community.
The Centers for Disease Control and Prevention asked the National Academies of Sciences, Engineering, and Medicine to organize a workshop to discuss how the adoption of SI units for radiation protection in the United States could improve information exchanges and communications. The workshop examined international experiences in transitioning to SI units for radiation protection and discuss possible steps towards adopting the exclusive use of SI units in the United States.

Workshop Summaries Resulting from this Event
Most countries in the world use the SI (Système International, also known as the metric system) units for radiation measurements in commercial and technical activities. The United States, in contrast, uses a mix of SI and conventional units for radiation measurements, despite 30-year-old national and international recommendations to exclusively use SI. Radiation professionals in the United States are faced with the need to understand bot... More >>
