1 Handmade Geiger Counter with GM tube by Yasuyuki Onodera 25 Mar As you know, there was nuclear crisis in Japan. People need to keep away from radiation. Geiger counter is a radioactive detector. Section 1 Introduction There is radioactivity. The radioactive rays are invisible. We are suffering from it. The sun is a nuclear fusion reactor. Are the radioactive rays dangerous? How far do we take a distance from radioactive obstacle for our safety? I had lots of questions. First, I had wanted to measure radioactivity to understand the effect from the field. Geiger counter, dosimeter, is a measurement device. But it is very expensive. I made it with low cost. And I had success to count it. Caution: Use this document at your own risk! Danger high voltage in the Geiger counter. Section 2 Geiger Muller tube In 1925, Johannes Wilhelm Geiger who was a physicist in German and Walter Muller who was a student, invented a sensor to detect radioactive rays. In short, GM tube. Although the high voltage is needed for the center of cylindrical metal (negative pole) by what has arranged metal stick (anode), radiation is measurable one by one. The intensity (speed) of radiation cannot be measured. Quantity (number) is measured. Sensitivity can be comparatively made high. It is fit for detection of alpha rays and a beta ray. Although a gamma ray is also detectable, it is said that the detection probability is about several %. The Geiger Mueller counter is decompressed by 0.1 atmospheric pressure, and it fills up with inactive gas (Ar, helium) and halogen gas (bromine) as continuation electric discharge prevention. Voltage from DC 500V to 700V necessity. The voltage region suitable for this measurement is called Plateau voltage All rights reserved by Y.Onodera. Page 1
2 Window(Mica) Inactive gas Radioactive rays Electron Ion + Electric discharge prevention gas Cylindrical metal (cathode) Geiger muller tube device Work theory of GM tube. 1. Radiation (alpha, beta, gamma) carries out incidence. It collides with a gas molecule (inactive gas), and gas is ionized (ionization). 2. The generated electron is accelerated by high voltage field. 3. Further, an acceleration electron collides gas and is excited. 4. When the excited gas return to a base state, ultraviolet rays are generated. 5. Ultraviolet rays ionize gas and cause an electronic avalanche. 6. An electronic avalanche reaches the anode and is detected as a pulse. 7. On the other hand, plus ion gas reduces voltage field. 8. Thereby, the electronic avalanche ceases. 9. Plus ion gas moves to the negative pole(since it is a molecule, movement takes time) All rights reserved by Y.Onodera. Page 2
3 10.Current flows, and an electronic avalanche is promoted. 11.An electronic avalanche does not stop. Then, electric discharge prevention gas is put in. 12.Electric discharge prevention gas receives a plus electric charge. 13.Although electric discharge prevention gas reaches the negative pole, an electronic avalanche is not promoted at this time. 14.Electric discharge prevention gas returns to a molecule All rights reserved by Y.Onodera.

There were three active reactors and three nonactive reactors. All active reactors went to shutdown automatically. But all power plants had lost power to control themselves. Tsunami had broken them. So cooling system couldn't work after shutdown to go safe mode. Uncontrolled hot fuel rod had lead to three hydrogen explosions. I could detect a radiation at 15 Mar in Tokyo Japan. Tokyo is located 250km south side of the nuclear power plants. It was north wind. Radioactive fog was moving in Tokyo. This Geiger Counter was very useful for us.
