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.
In the realm of scientific observation, luck is granted only to those who are prepared. - Louis Pasteur
