☢ Gundersen Radioactive Sulfur-35 = Nuclear Chain Reaction at Fukushima Daiichi Reactors ☢

☢ Fukushimas China Syndrome With Radioactive Steam and Media Blackout ☢

Arnie Gundersen came out with a new video yesterday. People have been talking a lot about the smoke and steam that comes out from cracks at the Fukushima Daiichi Nuclear Plant. Like today if you were to look at the live cam you would notice that the fog / steam around the reactors are so thick that the reactor units are not even seen on the cam.

The talk going around is that the nuclear core have melted through the containment and is now in contact with the groundwater, causing the smoke and steam that we see. Russia Today asked Mr. Gundersen to comment on this and he declined. Because to him there isn't good solid engineering data to make any conclusive remarks on the situation, Gundersen says he don't think there is enough data to either support or refute it. And I would probably do the same if I where in his position at this point.

Gundersen goes on to talk about much more important issues, like the finding of radioactive Sulfur-35 in the atmosphere in California. The finding have been confirmed but why there was radioactive Sulfur-35 have been left out. It turns out that when saltwater is radiated with neutrons it turns into Sulfur-35. What this means is that a nuclear chain reaction is still going on to some extent and continue to contaminate the surronding environment and upper atmosphere with large doses of radioactivity. TEPCO on the other hand have stated that it's reactors have been shutdown. But this can't be the case if Sulfur-35 is found in the air.


This is the text from Fairewinds site.

Newly released neutron data from three University of California San Diego scientists confirms Fairewinds' April analysis that the nuclear core at Fukushima Daiichi turned on and off after TEPCO claimed its reactors had been shutdown. This periodic nuclear chain reaction (inadvertent criticality) continued to contaminate the surrounding environment and upper atmosphere with large doses of radioactivity.

In a second area of concern, Fairewinds disagrees the NRC's latest report claiming that all Fukushima spent fuel pools had no problems following the earthquake. In a new revelation, the NRC claims that the plutonium found more than 1 mile offsite actually came from inside the nuclear reactors. If such a statement were true, it indicates that the nuclear power plant containments failed and were breached with debris landing far from the power plants themselves. Such a failure of the containment system certainly necessitates a complete review of all US reactor containment design and industry assurances that containments will hold in radioactivity in the event of a nuclear accident. The evidence Fairewinds reviewed to date continues to support its April analysis that the detonation in the Unit 3 Spent Fuel pool was the cause of plutonium found off site.

Third, the burning of radioactive materials (building materials, trees, lawn grass, rice straw) by the Japanese government will cause radioactive Cesium to spread even further into areas within Japan that have been previously clean, and across the Pacific Ocean to North America.

And finally, the Japanese government has yet to grasp the severity of the contamination within Japan, and therefore has not developed a coherent plan mitigate the accident and remediate the environment. Without a cohesive plan to deal with this ongoing problem of large scale radioactive contamination, the radioactivity will continue to spread throughout Japan and around the globe further exacerbating the problem and raising costs astronomically.

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.
