re: chernobyl.about ten years ago, the lifespan was about half normal for mammals in the “hot” areas. Today it’s safe levels except a few spots like the sarcophagus. .Having been messed up all my life from Hanford’s fallout, one wonders what the lives of people downwind that survived are like now. A lot of this stuff is chronic, rather than the weird stuff seen in bad scifi movies or econut dreams..While particles don’t go nearly as far as the media claims (an example is some lovechild spiking sensors in this country with hospital I-131 and then claiming that somehow iodine particles ~4130 times the density of air managed to make it despite winter storms for 5000+ miles from Fukushima), those within a few hundred miles of chernobyl would definitely be affected. .A few particles, say at extreme range of say, 1000 miles, won’t harm because there would be far too few. At 100 miles, the effects would be pretty severe, like they were in Baker and Wallowa counties in Oregon, with unexplained thyroid cancers, thousands with thyroid problems, and a lot of people like me who had weird anomalies (like 60% immune system) show up..The only good news is that particles like those released from Chernobyl and Hanford don’t last long. In a quarter century, people can now live and farm in the “dead zone” with only a few exceptions. Some never moved out and survived, presumably because they were in low dose areas.
