Radiation studies involve the examination of how different types of radiation, such as ionizing radiation and non-ionizing radiation, affect living organisms and the environment. Researchers investigate the sources of radiation, including natural sources like cosmic rays and man-made sources such as medical imaging devices. These studies help in understanding the potential health risks associated with exposure to radiation. The findings from radiation studies are crucial for developing safety guidelines and regulations. Organizations like the World Health Organization (WHO) and the U.S. Environmental Protection Agency (EPA) use this research to inform public health policies and ensure that radiation exposure remains within safe limits for both individuals and communities.
