While the Geiger counter is on (powered), the bare PC board contains exposed high voltage components. Even when the circuit is turned off (power is removed) the capacitors still may hold a high voltage charge.A project box or case is recommended and available for separate purchase based on the option chosen for your kit.
This Geiger counter outputs audible click and will blink a LED with each radioactive particle it detects. In addition it has two digital outputs that may be connected to a number of accessory instruments; a data logger, Digital Meter adaptor that outputs an approximate radiation level, RS-232 adaptor to plot radioactivity on a PC, and true random number generator. Using the analog meter adaptor, the geiger counter can approximate 3 radiation ranges: 0 to 1 mR/hr, 0-10 mR/hr and 0-100 mR/hr (or 55 mR/hr depending upon GM tube selected). This Geiger counter with a DMAD is compatible to our free Radiation graphing and monitoring software.

The Digital Meter Adapter is a expansion module for analog Geiger counters that adds many features to your analog Geiger counter. The DMAD reads positive +5V pulses from an analog Geiger counter. It counts each pulse that represents a radioactive particle detection. The pulse counter has two selectable time periods; a one second time period for Counts Per Second (CPS) and a sixty second time period for Counts Per Minute (CPM). Another function is Random Number Generator. This allows each radioactive particle detected to generate a true random number. The last feature is a serial output that when used in conjunction with an optional TTL/USB Cable output the count data to a Windows Program. The DMAD has the three most popular functionalities in one module to enhance the capabilities of analog Geiger Counters.
Detect particles and/or make a cool random number generator with this handsome Geiger counter kit. This easy-to-make pack of parts turns a simple Geiger-Muller tube (included) into a portable blink, beeping radiation detector. You can also connect an FTDI friend to the header, to get serial output for datalogging on your computer.We put this kit together in a couple of hours and hand lots of fun bringing it around and listening for ticking sounds near granite countertops, vintage glow-in-the-dark clocks & watches, old FiestaWare, chunks of Uranium, etc. It includes all components (PCB, tube, & parts) but you will need basic soldering tools and two AAA batteries to complete it.Please note! This Geiger Counter kit is for EDUCATIONAL PURPOSES ONLY. Don't even think about using it to monitor radiation in life-threatening situations, or in any environment where you may expose yourself to dangerous levels of radiation. Don't rely on the collected data to be an accurate measure of radiation exposure! Be safe!

Detect beta and gamma radiation with your own portable Geiger counter! The MightyOhm Geiger Counter Kit++ includes all components needed to build a completely open source, hackable, working Geiger counter. The Kit++ includes a Geiger tube, Acrylic case, and AAA batteries.
Back in the 1960s, we had a neighbor who was a \"rock hound\", and one day he was sitting on his bed fiddling with his geiger counter when he noticed an unexpectedly high reading. He traced it to his bedside table that had four Mexican tiles as decoration. Needless to say, he moved the table elsewhere before going to bed. (He lived in a furnished apartment, so wasn't at liberty to dispose of the table.)I'd humbly suggest that uranium glass (and other radiation sources) be stored as far away from where you normally are as possible (and preferably with some intervening shielding).
During lab periods, students build their own Geiger counter, and then characterize their counter, the background radiation in the room, and its shielding properties, using the tools and software described below.

Not too long ago, I learned that it is possible to buy a kit to build a basic Geiger counter, for only around $100! I jumped at the opportunity and, after some minor modifications, started checking for radioactivity!
The biggest challenge in building a Geiger counter is, in fact, finding efficient radioactive sources of radioactivity to test it on! As a first test of a new counter, simply turn it on: you will find it clicks every few seconds. These clicks are mostly due to natural radiation in earth-bound sources, such as the building material in your home. A small number of these clicks are the result of high-energy particles produced in the upper atmosphere via radiation from outer space: cosmic rays. (For a history of cosmic rays, and more details, see my old guest post on Scientific American.) My counter clicks roughly about every 10 seconds, though keep in mind it is a random process and the count will sometimes be a little faster or a little slower.
Depending on the elevation and the type of Geiger counter, a typical natural background radiation level is anywhere from five to 60 counts per minute or more. Because background radiation rates vary randomly, you might see that range standing in one spot. It is important to understand that the Geiger counter indicates when an ion pair is created, but nothing about the type of radiation or its energy.
Other types of instruments can provide an exposure rate (expressed as milliroentgen per hour or mR/hr). These counters must be calibrated to read a particular type of radiation (alpha, beta, gamma, neutron, x-ray) as well as the amount of energy emitted. The reading will only be accurate for that type of radiation and that energy level. And these instruments need to be calibrated regularly to be sure they are providing correct information over time.
For more sophisticated environmental radiation readings, check out the Environmental Protection Agency's nationwide system, RadNet. Using equipment far more sensitive than a Geiger counter, it continuously monitors the air and regularly samples precipitation, drinking water and pasteurized milk.
By the way, the Geiger counter is also called a Geiger-Mueller tube, or a G-M counter. It was named after Hans Geiger, a German scientist, who worked on detecting radiation in the early 1900s. Walter Mueller, a graduate PhD student of Geiger's, perfected the gas-sealed detector in the late 1920s and received credit for his work when he gave his name to the Geiger-Mueller tube.
A Geiger counter can be a niche tool for preparedness, but it is one of those tools that is irreplaceable when you actually need it. There are many types of Geiger counters available and they are not just used during radiological emergencies. 781b155fdc
