Three basic concepts apply to all types of ionizing radiation radiation protection (time, distance and shielding). 150 meters of air halves ionizing radiation. So 1.5 kilometers of air is 1024 times less and 3 kilometers is 1 million times less and 4.5 kilomters is 1 billion times less Get down to a background exposure of …
