Did any of the Chernobyl divers survive?
The three men would live longer than a few weeks and none would succumb to ARS, as modern myth would have you believe. As of 2015, it was reported that two of the men were still alive and still working within the industry. The third man, Boris Baranov, passed away in 2005 of a heart attack.

The control rods, according to the synchro indicators, seized at a depth of between 2 to 2.5 meters (6 ft 7 in to 8 ft 2 in) instead of the entire core depth of seven meters (23 ft), leaving the graphite displacers inserted into the reactor and accelerating reactivity.
