In the US serious radiation exposures?

In the U.S., serious radiation exposures can occur from various sources, including medical procedures like X-rays and radiation therapy, occupational hazards in certain industries, and accidental releases from nuclear facilities. These exposures can lead to acute health effects, such as radiation sickness, and increase the long-term risk of cancer. Regulatory agencies, like the Environmental Protection Agency (EPA) and the Nuclear Regulatory Commission (NRC), set safety standards to minimize these risks. Public awareness and emergency preparedness are crucial in mitigating the effects of serious radiation incidents.
