☢ Two Tupolev TU-95 Strategic Bombers From Russia Circle Japan Fukushima Sep 8 2011 ☢

This is an interesting story that came out. It seems that the Russians are doing some radiation measuring of their own. Now they don't say why the had two strategic bombers to circle Japan but it is kinda obvious why they did it. Because they useed the TU-95 Strategic Bombers. The TU-95 was the aircraft used by the Russians (Sovjet) back in the 1950 to drop atomic bombs. The biggest nuclear bomb ever made was also dropped by the Tupolev TU-95. So it's a given that these aircraft would be stuffed with all kinds of measuring equipment.

Read the transcribed story or watch the news report.

Japanese defence officials say two Russian bombers took an unusual corse circling around Japan. The defence ministry say two Tupolev TU-95 Bombers from the Russian airforce approached Japanese airspace near the strait of Shima on Tursday morning.

Fighter planes from Japan Air Self-Defense Force (航空自衛隊, Kōkū Jieitai) scrambled to track to bombers. The aircraft leader flew southword over The East China Sea and then south of Okinawas main island afterwards it moved to the Pacific side before scruding along the Japanese archipelago to go northword. The bombers continued flying over the strait of soya while being fueld mid-air. They then headed south on the Japan Sea side before leaving areas near Japan. The defence ministry says the bombers did not violate Japanese airspace, but it was an unusual route for any Russian military aircraft. The Russian airforce have been active around Japan recently. Bombers and spy planes have approached Japanese airspace 5 times since last month.

Russia revealed the flying and says 10 aircraft from Japan's Air Self-Defense Force and South Korea's Air Force tracked them.

The Tupolev TU-95 Strategic Bomber was also the aircraft used when the most powerful thermonuclear device was detonated in October, 30th, 1961 at 11:32 am. The Tsar Bomb was dropped from a bomber TU-95 from 10,5 km height. Destruct of the bomb happened 4500m high above sea level. The explosion yield reached 58 Mt in TNT equivalent.

The explosion results of the device called Tsar Bomb:
The explosion’s “nuclear mushroom” rose 67km high, the diameter of its double-level “cap” reached (at the highest level) 95km. The Fire ball of the explosion with the radius about 4,6km reached the land surface that is not typical for the nuclear air bursts. Radiation caused third degree burns at the distance of 100 km. The burst wave doubled the globe three times. Atmosphere ionization became a reason of radio communication interference even hundreds kilometers away from the testing area that lasted 40 minutes.

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.
