What is Background Radiation? - Definition from Safeopedia
WebRadiation Protection. Radiation describes any process in which energy emitted by one body travels through a medium or through space, ultimately to be absorbed by another body. Radiation can be classified according to the effects it produces on matter, into ionizing and non-ionizing radiations. Ionizing radiation includes cosmic rays, X rays and ... Web23 jul. 2024 · This is clearly higher than background (remember, with a GM, background is normally around 50-100 cpm), but it’s not a danger to anybody. As a radiation safety professional, I’d be inclined to clean up the contamination if I could unless it were a large-scale emergency with other more pressing problems. enchanted roma st
