Neutron ray was measured in Tokyo.
This is the screen shot of the moment when they measured it in a car, around Toranomon, where is near Tokyo tower.(10/18/2011)
Before 311, average neutron ray was 4 nSv/h.
After 311, it' 464 nSv/h (116 times higher than before 311).
Neutron ray is emitted from Uranium 235.
In one of the worst hot spots in Chiba, Kashiwa shi, citizens detected Uranium 235.
It was right beside a bench in Matsuba daiichi kinrin park.

In Kashiwa, even from the height of 1.2, they can measure Uranium 235.
They are all scattered on the ground and they all emit neutron ray.
Here is the video of the moment when they measure neutron ray.%uFF08In Tochigi%uFF09
Neutron ray can not be measured by most of the Geiger counters.
and it' way more harmful to human body.
According to the worst pro-nuc safety standard ICRP60:
Tumor risk: 3~200 times higher than gamma ray
Possibility to shorten your life by cancer: 15~45 times higher than gamma ray
Genetic transformation: 35~70 times higher than gamma ray
Chromosomal abnormality: 40~50 times higher than gamma ray
Genetic impact for mammal: 10~45 times higher than gamma ray
This is why I warned that dosimeters makes you blind.
There have been a lot of the cases such as nosebleed, fatigue (bura bura disease), immune trouble etc..
They have been labelled as "harmful rumor" because "air dose" is too law to cause those symptoms.
However, this measurement of neutron rays makes everything clear.
Fear is always in the blind spot.
Now Uranium 235 is all around in Tokyo, which came from MOX with Plutonium.
They keep emitting neutron ray.http://fukushima-diary.com/2011/10/breaking-news-neutron-ray-measured-in-tokyo/?utm_source=feedburner
