It has been said that the issue has been over exagerated by the media and fueled by TV appearances of so called experts calling it a disaster who it turns out work for G. Soros companies.
The fuel rods are contained within 3 chambers, inner, middle and outer.
The first explosion showed the most outer containment concrete housing being destroyed by the steam build up but the two other containment housings apparently remain in place. It is possible I believe that even a meltdown could be contained within the most inner chamber.
Chernobyl it seems did not have any such containment features.
It may be that the radiation leak may not be as bad as we are being led to believe by the media.
Maybe someone has more knowledge about about this..
