These numbers aren't a big change from estimates 5 months ago.
42% of Chernobyl's Cs emission, but much lower land deposition - only 21% of total Cs emissions hit land.
And this is from 3 or 4 separate failures at old ill-prepared sites following a once-in-a-thousand-year quake which hit a chain of volcanic islands which are plagued by quakes.
Emission per failure is nearly a full order of magnitude below Chernobyl.
Total land deposition is also nearly a full order of magnitude below Chernobyl.
The lesson is to improve your game, not loose your cool.
Children begin by loving their parents. After a time they judge them. Rarely, if ever, do they forgive them. - Oscar Wilde
