North Korea announced on 7 April that it had discovered traces of radioactive materials from Japan’s Fukushima Daiichi nuclear plant, though at levels below that deemed dangerous. In response, the North’s state-run TV also reportedly ran a special on how to prevent radioactive contamination and flush it from your body, including advising people to wear raincoats in the rain, use face masks, and have, “seaweed, water and beer […] to prevent radioactive materials staying in the body.”
If nothing else, the beer should at least make you feel better.
