'environuts!'
Exposure to high doses of radiation doesn't mean your face melts and you collapse into a pile of green goo. It can take years for you to succumb in the form of cancer.
But this other shash you came out with - that people who care about the environment want to see it destroyed in order to avoid embarassment?
You could then assert that the CND would prefer to see a nuclear holocaust rather than face the ignominoy of world free from radioactive mushroom clouds. Oh the shame!
