What jobs can expose people to radiation?

All jobs. If you want to be technical, that is. Radiation is all around us. We can get it from both the sun and even the earth. Realistically, however, jobs in the medical and scientific fields pose the most exposure, but safeguards are taken to minimize human risk to practically zero. Be practical-minded when it comes to concerns about radiation. There's a lot of paranoia and mis-information around.
