Radiation Posted Areas For High Radiation. There are many high natural background radiation areas around the world where the annual radiation dose received by members of the general public is several times higher than. Minimum requirements for entry into high radiation areas where dose rates exist such that a person could exceed a whole body dose of 1 rem in one hour shall include those items.
