Three experiences I’ve had: 1) Placing a Geiger counter against a brick wall and measuring the natural radiation. 2) Discovering that one of the buildings in my condo complex has a ventilation system for the radon. 3) Standing before a large cloud chamber in a science museum and actually seeing the unbelievable amount of cosmic radiation that constantly penetrates everything.
Conclusion: There is no such thing as NO radiation, just more or less radiation.
