☢ [Video] New Chernobyl Shelter Into Final Construction Phase ☢

It has now been 4 years since the Fukushima disaster and now finally after 29 years the biggest engineering project in history, is entering it's final construction phase. The giant steel arch of Ukraine have been built to seal off nuclear fuel buried inside reactor four which blew up in 1986. It has taken 29 years and 40 countries to acquire the money to make such a engineering project.

2.15 Billion Euro Chernobyl Arch is big enough to house the Statue of Liberty

The huge steel arch will entomb Chernobyl's reactor four, and slash the risk of another radioactive disaster. Standing 360 feet (100 meters) tall, and 843 feet (260 meters) wide, the arch is held together by 680,000 bolts. Built by 500.000 workers the giant radioactive arch of Ukraine is big enough to house the Statue of Liberty.

The shelter, will house the nuclear reactor damaged in the 1986 disaster, and the old concrete structure built to cover it which is approaching the end of its life.

The safe confinement is expected to reduce radioactive emissions drastically.

But the 30-kilometre exclusion zone will remain contaminated.

“The area of exclusion zone will not be free of nuclear waste because there is the intention to have the nuclear waste storages in the exclusion zone, so there will be a permanent waste management operation,” said Vince Novak, Director of Nuclear Safety at the European Bank for Reconstruction & Development (EBRD).

Once ready, the shelter will be pushed onto rails to cover the reactor. It is hoped to become operational by the second half of 2017.

Experts say it will be another 300 years before it’s safe to live in the area.

“The ark is protecting the sarcophagus where there’s a lot of nuclear and toxic waste. It will be safe to live here after at least 10 radioactive half-lives have passed. An average radioactive half-life lasts 30 years,” said Volodymyr Verbytskyi, an engineer controlling the exclusion zone.

So the immediate area will remain a ghost town.

The cost of the shelter is 2.15 billion euros.

The EU, members of the G7, Russia, Switzerland and other countries are all donors with the EBRD contributing 675 million euros.

Euronews correspondent Sergio Cantone reports from Chernobyl:

“So the construction of the sheltering structure continues according to schedule. The biggest problem will come afterwards and it’s about removing all the radioactive elements in reactor number 4. At the moment a technical solution seems still to be a long way off.

So just like Fukushima there is no technical solution to the continuing contamination of the environment by "super safe" nuclear power.

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.
