how are you supposed to avoid low doses of ionizing radiation? it’s naturally occuring. You can’t go outside, eat food, or heaven forbid you fly. I agree with mountainlion, sounds like no background in radiation. BTW which types of radiation are ionizing? :)
Ionizing (or ionising) radiation is radiation composed of particles that individually can liberate an electron from an atom or molecule, producing ion-pairs. [...] US Federal Communications Commission material defines ionizing radiation as that with a photon energy of greater than 10 eV (equivalent to a far ultraviolet wavelength of 124 nanometers).

They even offer an example:
The exposure caused by Potassium-40 present within a normal person.
I guess there is a huge market out there for some process to remove Potassium-40 from everyone and everything that lives :-) After that is done, the next task would be to remove all the granite rocks from Earth, somehow. Ultimately, of course, since Earth is inherently radioactive, we have to get rid of the planet.
