I have a question about different kind of radiation. If I have a reading with 100 CPM natural background vs. a reading with 100 CPM x-ray radiation. Is there a difference in terms of health issue. Which is more dangerous or is 100 CPM always the same threat ?
It's very similar, since we don't know if the background detected is also xray. But if we consider the same dosage/energy and same area of penetration, then they're very similar. Because the background detected is a mix of beta/gamma/xray.
