What is the U.S. average yearly dose equivalence the general public receives from both natural background and man-made sources of radiation?

The average yearly dose equivalence that the general public receives from natural background and man-made sources of radiation is approximately 620 mrem. This figure encompasses various contributions, including cosmic rays, radon gas, terrestrial radiation, and medical procedures, as well as contributions from other man-made sources like nuclear power plants and medical imaging.

Having an understanding of this average dose is significant for radiological workers as it provides context for assessing exposure levels, understanding regulatory limits, and enhancing safety protocols. Since the average dose combines both natural and artificial sources, it illustrates the omnipresence of radiation in our environment. This knowledge is crucial when training to manage and assess radiation exposure appropriately in different settings.
