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’s 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.

1.2 m high from the ground

Background 0.372 μSv/h
80.0 keV,　Unsorted type of radioactive material = 254 Count
191 keV,　LEU（low enriched uranium = 180 Count
594 keV,　Cs-134 = 221 Count
655 keV,　Cs-137 = 208 Count

15 mm high from the ground

Background 0.628 μSv/h
30.2 keV,　Cs-137 = 621 Count
188 keV,　LEU（low enriched uranium = 156 Count
594 keV,　Cs-134 = 467 Count
654 keV,　Cs-137 = 412 Count

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.（In Tochigi）

Neutron ray can not be measured by most of the Geiger counters.

and it’s 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.

Lytro camera hands-on (video)

You knew Lytro was up to something, but with its infinite focus light-field powered camera out of the bag, how does it actually stack up in real life? In a word: novel -- you certainly won't be tossing your regular camera for this shooter, at least not in its current incarnation. Still the concept of shoot now, ask focus questions later is revolutionary, so hop on past the break for our initial impressions.

Right off the bat, you'll notice its diminutive size. If we're frank, we were expecting something more akin to a DSLR -- visions no doubt conjured by the immense arrays used to do this sort of wizardry back in the day. Its small, beautifully made, anodized aluminum body reminds us of a cross between an iPod Nano and an iSight camera -- inspiration that isn't only skin deep, as Lytro's desktop software (which you'll need to open and export .lfp files) is currently Mac only, with a Windows version in development.

Functionally, it's pretty simple to use. You manipulate the device via two buttons on its rubber coated end -- one turns it on, the other snaps photos. Captures are seamless and instantaneous, thanks to its zero-lag focus, and zooming is a similarly painless affair controllable on the grooved line across the device's top. As for image transfers, they're accomplished by connecting to a microUSB port on its bottom -- hidden behind a flap, of course.

Most of your interaction with the device takes place on its glass-encased 1.46-inch touchscreen, where you'll be able to frame and view your shots. Contrast isn't stellar, but the touch functionality worked great as we swiped through stills, stopping only occasionally to tap and refocus on-camera. It's a pretty no-frills UI, as there aren't any shooting modes or controls visible other than a battery life and storage meter, and settings menu.

Finally, those pictures can be slung onto Lytro's desktop client, allowing near pixel-perfect uploads to the company's servers, embeddable on Facebook, Twitter or anywhere that takes an inject code. Those embeds are Flash or HTML5 (depending on the device) and allow friends who encounter them to refocus to their heart's desire.

For now, it really is just a novel toy. A $399 toy that's certainly within reach for the photography junkie in your life, eager for a new twist on an old concept. That may or may not describe you, but mark our words -- when Lytro integrates this kind of tech into a larger, more potent shooter: game over.
