The Radiation Exposure Compensation Act (RECA) is a law that helps people who were hurt by radiation when they worked at the US government's atomic energy sites. The US government made these sites so they could test atomic weapons and nuclear energy. Because of this, some people who worked there were exposed to radiation, which made them very sick or even killed them. RECA is a law that helps people who were hurt by this radiation by giving them money, medical care, and other benefits. It also helps their families if they died. So, if you or a family member were hurt by radiation while working at one of these atomic energy sites, RECA can help you get the things you need.
