Ionizing radiation is currently fairly widely used to disinfect the seriously contaminated US food supply (and those of other countries). I'm wondering if many people know about this, and do you care (or, at the very least, would you want to know if the food you're buying is irradiated?). {It's actually not really radio active (for the most part), however, a 4.5kilGray dose is equal to 150 million x-rays. The doses permitted by the FDA vary, but most doses are above this level (fruits and vegetables, get a max of 100,00 rads (1 kiloGray), poultry gets 450,000 rads (4.5 kiloGray), for red meat, 700,000 rads (7 kiloGray), for spices 3,000,000 rads (30 kiloGray).}
