☢ Typhoon Roke Make Landfall On Japan's South-West Coast - More Damage To 11 March Earthquake Tsunami Region ☢

More than a million people in central Japan have been urged to evacuate as the country braces for the arrival on Wednesday of a powerful typhoon.

Reports said evacuation warnings had been issued to 1.3 million people, including 800,000 in the city of Nagoya, 170 miles (270km) west of Tokyo.

Typhoon Roke is thought to have killed five people even before it makes landfall. Police in Gifu prefecture said a nine-year-old boy and an 84-year-old woman were missing after reportedly falling into a swollen river. The body of a middle-aged man was discovered in a river in Nagoya early on Wednesday morning.

Rolling TV weather forecasts warned that Roke would make landfall on Wednesday, bringing torrential rain and violent winds.

It is expected to cling to Japan's south-west coast before moving north-east over Tokyo and on to the north-east region affected by the 11 March earthquake and tsunami.

Nuclear officials played down fears the typhoon could cause further damage to the Fukushima Daiichi power plant, where workers are battling to cool reactors that melted down in the March disaster.

A spokesman for Tokyo Electric Power, the plant's operator, said cooling systems used to keep the reactors stable would not be endangered by the typhoon. Every possible measure had been taken to prevent leaks of radioactive water, he said.

The meteorological agency warned that rivers in parts of central Japan were overflowing. NHK television showed residents in some areas wading through knee-high water.

"In Aichi the heavy rain is causing some rivers to overflow," an agency official told reporters. "I would like to ask people to exercise caution against potential disasters from torrential rain, strong winds and high waves."

Roke's arrival comes two weeks after typhoon Talas triggered floods and mudslides that left 67 people dead and 26 missing.

The meteorological agency described the eye of Roke as "very strong" and advised residents living in its path to exercise the "greatest possible vigilance".

The approaching typhoon has already caused disruption to factories and power output.

Chubu Electric Power, which supplies the central region, said it had lost 1,870 megawatts of hydropower output but there was no threat of electricity shortages.

More than 200 domestic flights were cancelled and bullet train services were suspended in some areas.

Toyota said it would close 11 factories in central Japan early to ensure the safety of employees. The carmaker said it would make up for lost output on subsequent shifts. Many commuters in Tokyo have been advised to leave work early.

By mid-morning on Wednesday the typhoon was located about 25 miles (40km) off the Kii peninsula in western Japan, generating winds of up to 135mph (216km/h).

It was expected to reach the Tokyo area in the afternoon and the tsunami disaster zone in the evening.

Heavy rain is expected in many areas of Japan's main island of Honshu through to Thursday morning, according to Kyodo news agency.

☢ The Radioactive Chat ☢

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.
