The first time the plant blew up. Now I might agree with you on the categoration that the levels that reached the west coast may not have been dangerous.
The plant did not “blow up”.
It was flooded by a tsunami. Engines and structures that maintain a cooling system were either destroyed or severely compromised. The result is cooling systems failure.
Get your facts straight or those of us with nuclear backgrounds will eat your lunch.
There is no “radiation” from Japan sweeping across the western coast of North America. Radiation doesn’t “sweep” thousands of miles from its source.
The same bull shit claim was made last year and included statements that tens of thousands of people had died. Since I live in southwest Washington State I knew those were all lies.
