workers who stepped in the water at Fukushima sustained significant radiation burns.
There are safer ways to work around these exposed cores but in some ways Fukushima is worse than Chernobyl. The workers who tunnelled under Chernobyl and laid concrete to stop further core intrusion into ground water avoided the more severe problem that now occurs at Fukushima.
The total exposed core material and the use of MOX also make the total expelled radiation greater at Fukushima, just that most of it has gone into the water rather than into the air.
