Equipment: Geiger Counter

Recently, I joined a new paranormal group. The founder assigned us each equipment to research and present to the group at the next meeting. I was assigned the Geiger Counter and thought I'd post it here, too.

-------------

What is your device and what is it used for in ghost hunting?

A Geiger Counter is a device used to measure radioactive particles. Most measure beta particles and gamma rays, but some also measure alpha particles. Alpha particles positively charged and are composed of two protons and two neutrons. Beta particles are negatively charged, as they are fast moving electrons. Gamma rays are electromagnetic radiation and are neutral.

A Geiger Counter is made up of a gas filled tube that briefly conducts electricity when it comes into contact with a radioactive particle as described above. The tube conducts a brief current and this will cause the device to click, move a needle, or light up (depending on the type of device one uses).

Geiger Counters are used in the paranormal community to measure paranormal activity, much the same as an EMF meter. Many investigators will take a baseline reading, and then during the investigation, keep an eye on the Geiger Counter for any strange readings. Obviously, it would also help if one wasn’t sure if dangerous radiation was present.

How do you use it?

Typically, there is a “read” button that one depresses to get the reading. A normal reading is 0 to 1, and a possible paranormal reading could be anywhere from 1 to 20, or strange needle movement.

How do you maintain it?

Check the battery- in many devices, the “test” button will test the battery. In older models, calibration might be necessary.

What kind of paranormal activity does it detect?

The theory is that the Geiger Counter may detect possible spirit manifestations, that might also be caught on video or audio devices.

Do I need any accessories for it? If so, what?

Extra batteries, dependant on the model. Some are available with remote sensors.

What are the drawbacks or controversies of using this device?

There are really old devices floating around that may need calibration. There have been people selling other types of radiation detectors as Geiger Counters. The devices can be expensive. They start around $30 for the old cold war versions (that may need calibration) and the newer ones range from $200- $2,000+.
