A giant radioactive fog cloud named “Thule” has appeared in Central California, USA. This layer of fog covers an area of 650 km and is the densest layer of fog ever recorded. Daily Mail version published documents about this phenomenon.

The National Weather Service has been sending out dense fog warnings for the Central Valley since last week. These reports state that “a thick layer of low-level radiation poses a serious risk to traffic.”
Over the past week, major cities such as Sacramento, Fresno, Bakersfield, Oakland and Stockton were the hardest hit. In total, more than two million people have faced the consequences of this phenomenon, the publication noted.
The authors point out that Thule has its onset each year in late November, peaking in December-January before dissipating in March. The problem, they say, is that this layer of radiation traps chemical particles emitted by industrial plants, leading to an increase in respiratory diseases among the local population.
In addition, in poor visibility conditions, the number of traffic accidents increases significantly. In particular, in 2007, due to fog on one of the highways, there was a major collision involving 108 vehicles.
