☢ Strange Fires at Fukushima Daiichi Nuclear Power Plant Aug. 6 2011 ☢ UPDATE 3 ☢

This is a follow up on the earlier:
☢ Strange Fire at Fukushima Daiichi Nuclear Power Plant Aug. 6 2011 ☢ UPDATE 2 ☢

I got some good comments about my last post trying to pinpoint the location of the Fukushima Fires going on. Some have put forth a very dark theory about what is happening. They claim that the Centralized Radiation Treatment Facility (area located behind the reactor 4 building) is in use to burn radioactive material on site. Another teory would be that they have built a facility next to reactor 3 to do the same. Burning radioactive waste sounds crazy, but the sad thing about this is that it is in use all over the world. There have been actions against this to little effect. Because it is considered safe when they use $200.000 filters made in Germany to capture the "fallout".


I can't say for sure this is what's going on because the location of the fires are still to me in the same area as the Common Spent Fuel Storage Facility. Looking at the pictures there is a hill in the background. If we take this hill and the tower drawn out in red into reference then to me it looks like the fire is in that area. But it's hard to say for sure, and with news of how radioactive material is indeed being burned around the world. Who knows what they really are up to. One thing is for certain, something is burning at the plant.

Why Fukushima’s “spent” fuel rods will continue to catch fire

By: Kirk James Murphy, M.D. Tuesday March 15, 2011 4:26 pm


Six of the spent fuel rod pools  are (or were) located at the top of six reactor buildings.  One “common pool” is at ground level in a separate building.  Each “reactor top” pool holds up to 3450 fuel rod assemblies.  The common pool holds up to 6291 fuel rod assemblies.  [The common pool has windows on one wall which were almost certainly destroyed by the tsunami.]  Each assembly holds sixty-threefuel rods. This means the Fukushima Daiichi plant may contain over 600,000 spent fuel rods.  The fuel rods once stored atop reactor 3 may no longer be there: one of the several explosions at the Fukushima reactors may have damaged that pool.
Now that we have partial meltdown in the reactor vessels – the part of the reactor where nuclear reactions are supposed to happen – in at least three of the Daiichi palnt’s six reactors, why bother with swimming pools for fuel rods?  Simple. Even after they are no longer usable to drive nuclear fission in the reactor vessels, the “spent” fuel rods are still highly radioactive.  Part of that radioactive energy is emitted as heat.  That’s no surprise: heat from radioactivity is the how the reactor core vessels generate the heat that drives the nuclear plant’s turbines to generate electricity.  The fuel rods don’t know whether they are in the core or in the pools: they keep emitting heat and radioactivity until the radioactive material decays into non-radioactive elements.  That process can take years, which is why spent fuel rods are still dangerous years after they leave the reactor core.
How can we prevent the spent fuel rods from bursting into flame once they’re out of the reactor core? The Fukushima plant – like many other reactors – keeps the rods in water, which absorbs the heat energy.  But the pools – like the water in a teakettle – will boil away unless new water is added.  After the Fukushima plant lost power in Friday’s 9.0 earthquake and got hit by the tsunami, the plant was no longer able to keep the pools topped up.

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.
