NHK: Researchers Simulate Fukushima Spread

"A group of Japanese researchers have created a computer simulation of how radioactive substances from the troubled Fukushima Daiichi nuclear power plant spread across the globe.

"Researchers at the University of Tokyo and Kyushu University on Wednesday released images of the simulation using a forecast system for air pollution and yellow sand.

"The simulation was based on the scenario in which contaminated air was vented from the crippled No.2 reactor building on March 14th, 3 days after the massive earthquake and tsunami.

"The simulation shows some of the radioactive material was carried 5,000 meters into the air by ascending currents of a low-pressure system that passed near Japan the next day.

"Computer images show the substances were then carried by westerly winds and spread over the Pacific Ocean.

"The images indicate that on the 4th day after being vented the substances reached the west coast of the United States, and on the 7th day they approached Iceland after crossing the Atlantic."

MAJIA HERE: This simulation only shows radioactive materials from reactor #2 and doesn't show spread of materials from #1, #3 and spent fuel pool #4.

Why is that do you think?
