My guess is the original reports of massive radiation leaks were the inaccurate (lies) ones. Massive amounts of deadly radiation being leaked fits the agenda, finding out the power plants were in fact safe does not.
As far as I know, it’s not possible to have a meltdown and have only a tiny radiation leak. Of course the corporation is going to say “not to worry,,,we have everything under control.” I don’t trust corporations any more than I trust government. Neither gives a rats about you. The bottom line for both is power and your money,,,not you.
