maybe jrv or someone who's more qualified on the engineering/pure sciences can explain it with some numbers i'd hesitate to toss out as anything close to hard and fast.

i'll just throw out what i'm seeing as fuzzy values i'm seeing as what a single modern reactor's probably in range of, then just extrapolate the rest basically based on the characteristics of radiation travels and how we think it's dangerous to us in short bursts and lingering and repeated low-level exposure. remember, relatively instant death short of being on site or near an exploding warhead takes serious contact with a not-insubstantial or pebble-sized bit of low-test shit, london's russian dissenter went down to a fucking suitcase of presumably about as enriched shit we can create. killed the dude carrying it, but we're not talking trivial, decayed shit in carried-over levels. so it's just another thing that might make you kick early to cancer, go buy some unfiltered luckies and enjoy what you're looking if you keep doing this daily for a few decades.

scale's so far off from being anything i'll worry about.
