Radioactive dusts Contaminate the soil with rainwater

Since the outbreak of the magnitude-9 mega earthquake and tsunami in the ocean of East Japan on March 11, 2011 that caused a series of explosions at the nuclear plant in Fukushima, an extensive radiation has leaked into the air. Through the atmospheric jet stream, radioactive dusts have crossed the Pacific Ocean, reaching the U.S. and Canada, and have polluted the entire North America.

The radioactive substances in the dusts include iodine131, cesium137 and xenon133 etc.

The radioactive dusts in the jet streams will mainly remain in the upper atmospheric layer and will not fall on the ground. Therefore, when you use any radiation detector to measure the level of radiation in the atmosphere, say for example the West Coast of the states and even Tokyo in Japan, you will find that there is no significant change in the radiation level.

On November 13th, 2011, the front-page headline of a local newspaper reported the findings of their reporters who were sent to Japan, in particular, Tokyo:

When they used the radiation detector to measure the radiation level in the air, they found that the level was normal. The Hong Kong Observatory has also measured the radiation level in the air as an indicator.

However, would it be too much of a sweeping statement if they just measured the radioactive level in the air?

In fact, when the radioactive dusts in the upper atmospheric layer fall on the ground with the rain, the radioactive dusts will accumulate and contaminate the soil on the ground. And so, the crops produced on this soil will also be contaminated by the radioactive dusts. When we eat these contaminated produces, we will also be contaminated by radiation.  

More interesting is, 3 days after the above news is released, another local newspaper used a completely antagonistic view to rebuke the findings of the irresponsible reporters 3 days earlier. They reported that when scientists and other science institutes from Europe and the U.S. measured the radioactivity of the soil in Japan, they found that the entire Japan is already under serious radioactive contamination.

Many people in the U.S. have already put videos of their own findings onto the internet earlier.

They collected rain waters on their cars with handkerchief on rainy days and then measured the radiation level of the handkerchief with radiation detector. They found that the radiation level was over 2 microsieverts per hour which is 10 times than that in the air, which is approximately 0.1-0.2 microsieverts per hour. 

From this, we can see that the earlier prediction about radiation contamination of the world in 2011 made by Webbot has already come true!
