☢ Homemade Geiger Counter For Under $10 ☢

Hello everyone,

With all this "recent talk" about Fukshima leaking 400 tons of radioactive plutonium water into the Pacific Ocean every day (experts say it has most likely been going on for 2 years already) the safety for ourselves and our loved ones are on many peoples minds. The one thing that enables you to see the dangersous presence of radiation is with the well known Geiger Counter.

DIY Geiger Counter
Homemade Geiger Counter
However not many people today can afford to get one because they do cost a bit. I remember that right after the Fukushima disaster most stocks of radiation meters where emptied so back then you could not even get one even if you had the money.

Well fortunetly you can make your very own homemade Geiger Counter for under $10. And if you already happen to have a simple volt meter you probably wont need more than a few bucks and some time to make one yourself.

MrTeslonian on Youtube recently made a very good video explaining and showing you exactly what you need to do. Some thin copper wire, small piece of aluminium pipe, aluminium foil (you could probably make due with just aluminium foil and not even have to use a pipe) and a volt meter set to AC Current and you are done. The great thing is that this simple homemade Geiger Counter will work for almost any form of radiation.


I am certainly going to give this a try, because it's a simple design, you don't need a lot of time and most likely have all parts avaliable around the house. It's proven and tested and shows that it works. If another disaster where to happen I strongly urge everyone that is anywhere near any sort of nuclear power plant to at least learn how to put one of these things together if you don't already have or know someone that owns an Geiger Counter.

Fukushima Reporters Turn Off Cameras When Radiation Spike

A few days ago journalists where allowed to take a bus tour around the Fukushima Daiichi Nuclear Power Plant. The reporters filmed and took photos of the damaged reactor buildings, although the journalists where not allowed to step outside during the tour it looked like things where somewhat under control at the plant.

But it was not, what the media don't show you is the fact that the tour was controlled. No free press to be found here. Fukushima reporters where controlled by a male on the bus. After the tour passed Nr. 3-4 reactor building probably heading to reactor Nr. 1 the dosimeters were showing 300 microsievert /hour. (Shown in the video text 0.3 = 300) The limit for workers at Fukushima is 250 microsieverts / hour...

ANN News from the private Japanese KHB Channel did a story and we can clearly hear how the reporters are being told to put down their cameras.

Author aristoman007 (youtube) Henry living in Japan 100km from Fukushima have been watching the news reports and here now gives us his take on this and what is already known to many of us about the continuing media blackout of the Fukushima Disaster.


36 reporters where on the tour, 19 of them belonged to the press club of the parliament and seven to the press club of the Fukushima prefecture management. The remaining ten journalist’s were reporters represented from abroad. Independent journalists and Internet reporters have not been granted access.

More media blackout from TEPCO and the Japanese media is clearly not FREE. Radiation levels where going up during the tour, although this is only my take on the video shown here we can see some static (audio and video cuts) this is a common thing when dealing with high radiation. Electronic equipment don't work well near affected areas.

Fukushima Radioactive Used Cars Sold Around Japan

Radioactive Used Cars Being Sold in Japan

One car emitted more than 300 times the legal amount of radiation

Cars that were contaminated by radiation during the March nuclear meltdown in Japan are finding their way into the reeling nation's used car market.

Vehicles from the area around the Fukushima Daiichi nuclear plant, which suffered a series of meltdowns after the earthquake and tsunami of March 11, were supposed to be destroyed. But unscrupulous dealers have registered them under new license plates and sold them, The Asahi Shimbun newspaper reported. Unable to export the cars, they're selling them in Japan.

Dealers have traditionally bought used vehicles in Japan and exported them to Russia and Southeast Asia, according to the Telegraph. In June, Russian police turned back a half-dozen used cars from Japan after finding they were contaminated with radioactove isotopes, according to the Interfax news agency. Authorities in South America, Australia and the U.S. have also stepped up inspection of new and used cars coming in from Japan.

Now, with testing also being conducted at Japanese loading docks, dealers are selling the potentially lethal cars on the domestic market.

Nearly 700 cars have been barred from export for exceeding the legal radiation limit of 0.3 microsieverts per hour. One van that was re-registered and sold within Japan was found to emit 110 microsieverts of radiation an hour.

The dealer who bought the contaminated van, which had initially been registered in the town of Iwaki, within the 18-mile exclusion zone, said he sold the vehicle even after knowing it was poisoned because he wanted the money.

"I decontaminated repeatedly after the test and retested the filter of the air conditioner, the wipers and tires, replacing them thoroughly, but the radiation level dropped only to 30 microsieverts per hour," he said. "I decided to sell the vehicle in Japan because I couldn't afford to lose the money."

Eye Problems - His Child Got Nosebleeds

This interview would not have been made possible to share if it were not for Fukushima Diarys translation of parts of the interview due to it only being in Japanese.

The video is only in Japanese so it's hard for us to understand what is said. If you still want to watch the video I noticed that it starts at 1:30 min in. Before that we only get to see the Independet Web Journal logo. Don't ask why they feel the need for have us stare at it for so long.

The things that are also said about the deaths of workers and police not being reported to the public and rest to of the world are also disturbing to hear. Some workers are also forced to work there even when their radiation detection meters show 1-2 Sv/h. Might be that they do it for extra money though, still a lot of deaths are not being reported.


The original video have now been taken down so we only have a part of the video to show you from Youtube.


Anyhow this this is parts of what's said and you can of course also find this same text at Fukushima Diary.
I highlighted parts of the text I feel is extra important for you.

A raged Fukushima citizen confessed everything at the interview with a journalist Iwakami Yasumi.

This guy, Mr.Sakuma is in Kawamata machi, where is east to Fukushima plant by 22km.

Even before 311, he had been having a problem in his eyes.

His doctor said he has a tumor in tear gland. He was having medical treatment but after the explosions, it went so bad that he couldn’t even close his eyes.

Having his 3 years old child have nosebleed, he decided to evacuate to Hachijo jima.

His family totally believes what the TV says so he was criticized hard but since he evacuated to Hachijojima, his eyes became better.

He runs motorcycle shop. He has 30,000,000 JPY load from banks so he had to come back to Fukushima.

He is aware of the health risk to live in Fukushima, but for the financial reasons, he must struggle being exposed.

His eyes get worse soon as he comes back to Fukushima. However, his doctors at Fukushima university asserts it has nothing to do with radiation.

Interview overview

1) 21 years old Fukushima worker died of cardiac infarct. It is not reported and police didn’t even do autopsy. He died when he was at home, and he was working at Fukushima plant since March to July.

2) Though everyone pays attention to reactor 1 to 4, actually reactor 5 and 6 are in crisis. Engineers from Hitachi are coming to the area to get it settled down but it’s concealed. It’s likely that they are going critical so Iodine 131 are measured in Tokyo or Iwate.

3) In the “worst” contaminated area,where is about 1 Sv/h or so, “unlisted” workers are forced to work. They are hunted in the downtown in Osaka, treated as disposable workers.

One of his friends had to go into reactor 3. When the person saw the area, it was full of debris and the counter showed about 1~2 Sv/h but then next morning, the area was perfectly clean. Because it needs sensitive work, it must have been done by humans.

They say, those disposable workers were forced to work in those situations, held captive until they die, and then marked as “missing”.

4) Police that guard within the 20km area border are not informed of the radiation level. (about 100 microSv/h when Mr Sakuma and his friend visited) and a lot of police are dead but it never be reported either.

5) He longs for the truth, so everything can give up living in Fukushima at least. Even if it’s revealed in 50 years from now, it’s too late.

6) Some of the radiation monitoring posts are taken away.

7) Local government requires citizens to report “lower” number of what the counter shows, so their radiation map shows lower than actual.

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.
