The National Academy of Sciences Nuclear Radiation and Studies Board is hosting a workshop to discuss establishing a registry for long-term health monitoring following radiological emergencies in the U.S. The public can register to attend either in person or by webcast. The workshop, "Challenges in Initiating and Conducting Long-Term Health Monitoring of Populations following Nuclear and Radiological Emergencies in the United States", will be March 12-13, 2019. Staff from Beyond Nuclear will be attending in person. Agenda topics include biodosimetry (examining damage to biological markers in the human body to assess how much radiation a person was exposed to), population monitoring and health screening, environmental impacts, and examination of existing health registries following the Chernobyl and Fukushima nuclear power meltdowns and explosions.
