Lactose Memes

Comparing lactose intolerance to radiation exposure is like comparing a paper cut to decapitation. 90,000,000 roentgens is roughly 900 Sieverts - that's about 180 times the lethal dose. Your test subjects wouldn't be worrying about dairy products anymore. They'd be atomically restructured into what we in the lab call "very dead." Fun fact: At that dose, their cells would be so thoroughly ionized they'd practically glow. Not from radiation - from being vaporized.
