☢ Fukushima Mini-Nuclear Bomb German Radiation Expert Warns After Uncontrolled Nuclear Fssion ☢

Given the reports of an uncontrolled nuclear fission reactor accident in Japan's Fukushima Munich radiation expert Professor Edmund Lengfelder warns of the possibility of a nuclear explosion ....

It would be "a kind of mini-nuclear bomb in the scale," said Lengfelder the dpa news agency. "The probability, however, I can not estimate at all." Nobody knows how much enriched uranium had flowed together in the manner in which the derelict nuclear power plant units.

This text have been partly translated with Google translate:

Lengfelder had after the meltdown at Chernobyl 25 years ago the Society for Radiological Protection and the Munich-based Otto Hug Radiation Institute. He cared for people with thyroid cancer today in the former Soviet disaster area.

Eight months after the meltdown in Fukushima the isotopes 133 and 135 of the gas xenon has been found, said Lengfelder. Since these isotopes are products of nuclear fission and only have a half life of about five days and nine hours, they could not come from the time of the accident in March. "There is a spontaneous fission - because of this anything can happen, even if one says, it is not likely. But what is to be kept of statements about probabilities, we have on 11 March saw. "At that time, had a severely damaged in this earthquake and unexpected strength of a tsunami and the nuclear power plant caused the meltdown.

In a functioning reactor control rods keep the chain reaction under control. "But in a meltdown this contol is no longer found," said Lengfelder.

As for the actual radiation exposure was given the total load since the accident, the recent nuclear fission is not of great importance. "But it does mean that (the operator) Tepco is even further away than previously claimed from getting things back under control." How long such a nuclear fission, was not foreseen. Depending on the amount and location of the fissile uranium, it could also last for years - and the quantity in Fukushima is very large, it go to tons.

In any case, the partial exclusion zone of 50 km is far too low. You must be at least 100 kilometers in the main northwest. In addition, the Japanese government has raised the limit for children to 20 millisieverts per year. "This is in Germany the maximum radiation dose for a nuclear power plant workers - but not for a child," criticized Lengfelder. It is expected that the cancer rate will rise sharply in the children, including birth defects in newborns are to be feared.

The treatment of the population was "inhumane," said Lengfelder. "For me, it is also inhumane, that in such a wealthy country like Japan, people still live in the gyms. . That there was not even on the Soviets, "The evacuation after Chernobyl have worked much better - and the limits are in Belarus today about three times more severe than in Germany.

Among the volunteers who have used the operator Tepco to clean up in Fukushima, it would be premature deaths in the coming years. "Chernobyl must proceed in analogy to one of them. But I'm skeptical that they will have more clarity on the Japanese as victims in the Soviet Union. "The Japanese government had lied to the people of Japan and the world about the extent of the disaster long. "Japan wants its technical aura not to bet on the game." Now we have the Japanese people decide whether they wanted to live with this risk the threat continues.

Lengfelder is for an immediate shutdown of all reactors. "When they are not properly insured, it means in the case of a super-Gaussian: The citizen is sitting on his injury. First we had Chernobyl, now we have Fukushima - what we need ?"...

For example, there are the words of the Lengfelder because of safety concerns from environmentalists vehemently criticized Czech Temelin nuclear power plant across the Bavarian border, serious problems with the welds. "If there happens a meltdown, and the wind blows from the east, the exclusion zone to reach Munich ."...

Geiger Counters - Radiation Detection Meters - Handheld Radiation Detector

When it comes to radiation detection meters you really have a wide field of gadgets to choose from, however radiation detectors are the most common to use. First of all if you need to know what type of radiation you are looking for. There are Alpha, Beta and Gamma radiation detectors. And also there is neutron emission of nuclear radiation. And all these different types of emissions have radiation detectors for a specific type of radiation that you can buy radiation detector for. Some also measure both Alpha and Beta. Others detect Alpha, Beta and Gamma. While others let you measure Beta and Gamma radiation.

What most people have use for though are Dosimeters you can buy a handheld radiation detector pretty cheap that are good addition to a survival kit. There are different kinds that you can use that will detect radiation. There are radiation badges that will tell you when radiation become high. Workers at nuclear power plants use these to inform them of how much radiation they have been exposed to. Now also children in the Fukushima prefecture have each been given a radiation badge so they know if they are exposed to radiation. Some come in the shape of a pen that you can carry in your pocket while other are made more compact so that you can attach them to your keychain. And then you have what is called a personal radiation monitor. These are also called Dosimeters and also normally called Geiger counters. Although not all use the Geiger-Muller Tube for the radiation detection some use a semiconductor instead. These and mostly the older geiger counters seen are pretty big to carry around, so they might not be best suited for a survival situation where you only need to carry the most important things. However if you have land and want to check radiation around the property and drinking water then these are the geiger counters to get because they are very well built units.

These are the once that you normally see people use. They have different units of radiation detection, because when it comes to radiation there are many standards used. some give the measurements in Rads, while other use Sieverts. Some have the maximum radiation value for the measured radioactivity quite low but they will still give you an idea of the amount of radiation in the area. With the units ranging from between background radiation 0.001 mSv/hr all the way up to 10 Sv/h. Normally a dosimeter will measure radiation in micro siverts per hour. If you were to walk into one of the reactor units at the Fukushima Daiichi Nuclear Plant you probably would get an error reading from your dosimeter because the radiation levels are so high there.

Note that some places outside the exclusion zone in Fukushima that are too radioactive for people to live in have areas where the radiation levels are above 30 Sv/h. So if you are in a area that have high radiation the radiation detectors would also there go off the scale. However Geiger counters or radiation detectors are still favored as general purpose alpha/beta/gamma portable radiation detectors and radiation detection equipment, due to their low cost and robustness. Most come with an LCD Display that show you the radioactivity in the area. Nowdays you will even get alarm sound and the possibility to connect the device to a computer. Either with a Infrared, Bluetooth or USB connection.

So if you look at the radiation detectors for sale that have this, then these radiation detection meters will allow you to make maps of contaminated areas that show where the radiation is high and low. This also will help you to see which areas are becoming more contaminated over time. With several nuclear reactors in the US and around the world located near fault zones that makes it a danger if a big earthquake would hit the area there is always a good choice to have a radiation dosimeter avaliable. I'm sure many in Fukushima would have been grateful to have dosimeters avaliable at the time of the disaster and I am sure you to would be grateful to have a geiger counter handy when you need one.
