What are the sources of radiation exposure in the United States?
Average U.S. Doses and Sources All of us are exposed to radiation every day, from natural sources such as minerals in the ground, and man-made sources such as medical x-rays.
What is the most common source of radiation exposure in the United States?
As can be seen, natural background radiation, also called “ubiquitous” since it is around us at all times, is the largest source of radiation exposure to humans (50% or about 3.1 mSv). Terrestrial and cosmogenic radionuclides enter the body through the food we eat, the water we drink, and the air we breathe.
What is the source of the highest radiation exposure?
By far, the most significant source of man-made radiation exposure to the public is from medical procedures, such as diagnostic X-rays, nuclear medicine, and radiation therapy.
What are the 4 most important sources of background radiation?
