http://chernobylgallery.com/chernobyl-disaster/radiation-levels/>LD50 (50% chance of killing you) is 5000 millisieverts (msv)>LD100 (guaranteed to kill you) is 10,000 millisieverts (msv), or 10 sieverts (SI). Death is guaranteed within "a few weeks" and can be as rapid as 12 hours.In 1986 in and around the reactor core was approximate 300 sieverts per hour, which is 30x the LD100.
The crane claw I talked about in
>>1116423is 336 microsieverts (usv) per hour, I fucked it all up. It would take 149 hours to hit the LD50, not 14.9. Likewise, the Pripyat cemetery is 22 microsieverts an hour.
I did have the estimates for just inside the sarcophagus correct though, 14 sieverts an hour, which is above the LD100 and 2.2x the LD50.
Again, the elephant's foot is estimated via mathematical calculation to be between 500 and 15,000 sieverts per hour. The reason the estimate range is SO STINKING LARGE is they were never able to get a good reading on it when it first formed due to being so horribly radioactive it fried all their equipment, and not really knowing its exact composition (they know it contains flammable graphite, plutonium-239 and -241, strontium-90, cesium-137, americium-241, and iodine-131. The iodine WAS the most dangerous but due to a very short half-life (8 days) it should mostly be gone, and the current biggest threat is the americium with its 430 year half-life and the fact it's still being produced as it's the decayed form of the pu-241 with its 14.4 year half-life.
While the strontium and americium/plutonium aren't particularly radioactive (EBq's of 0.010 and 0.003 respectively), there was SO MUCH of it (literal tons) it will be a significant health hazard for millennia. At the 430 year half-life it will take nearly 20,000+ years for 90% of it to degrade.
