What’s a Geiger Counter?
A Geiger counter is a tool that detects and measures ionizing radiation. They used to make use of a Geiger-Mueller tube, which might be one other identify for the machine. As you would possibly count on, Hans Geiger and Walther Mueller invented the unique tube in 1928. The detector they invented is comparatively low value and has only a few drawbacks for radiation detection. Because the Fifties, Geiger counters have adopted halogen tubes since they’ve an extended life and decrease working voltage.
Geiger counters are used for quite a lot of radiation-detecting functions. I used them extensively within the navy. Purposes they can be utilized for embrace:
Radiation dosimetryNuclear trade monitoringRadiological protectionMilitary mitigationExperimental physics
Geiger counters are additionally extraordinarily helpful for preppers trying to be ready within the occasion of a nuclear assault, EMP, nuclear accident, or area ionization occasion. The counters are sometimes not electromagnetically shielded, so it’s a good suggestion to retailer them in a Faraday cage to allow them to be operational after an EMP occasion.
What Can a Geiger Counter Detect?
A Geiger counter seems for ionizing radiation. Ionizing radiation is what you usually consider when speaking about radiation – radiation that detaches electrons from atoms and molecules. Indifferent electrons are known as ions, therefore ‘ionizing radiation’.
Subatomic particles emitted as ionizing radiation journey extraordinarily quick and might generate electromagnetic waves of excessive vitality. X-rays, gamma rays, and a few UV rays are ionizing types of electromagnetic waves. Infrared, microwaves, and radio are non-ionizing and aren’t deliberately detected by a Geiger counter.
The subatomic particles which are often a part of radioactive decay embrace
alpha and beta particles in addition to neutrons. Geiger counters usually look
for:
Beta emissions – Beta particles are the second largest emission, behind Alpha particles. They’re problematic in that they’re nonetheless sufficiently small to pierce most supplies, together with clothes. Though they don’t seem to be as damaging as Alpha particles, the dosage might be increased since it’s tougher to protect.Gamma emissions – gamma rays can pierce via a number of ft of radiation shielding and are absorbed into the physique. It’s arduous to mitigate gamma radiation besides by escaping the supply.X-Ray emissions – X-rays may also present the presence of Alpha particles. Alpha particles are the most important particles ionized and might be extraordinarily damaging via pores and skin contact, ingestion, and inhalation. Fortunately, membranes as skinny as a sheet of paper can cease them.
Detected radiation is displayed as a depend or a dose with Geiger counters. Units that solely present dosage are known as dosimeters. Units that solely present counts are known as radiation detectors. Each depend and dose measure radiation over a interval, mostly as Sieverts per hour (Sv/hr).
Some Geiger counters use audible clicks to provide the variety of ionization occasions detected. This permits the consumer to focus on issues apart from the radiation detector whereas nonetheless understanding the quantity of radiation in an space.
How Correct is a Geiger Counter?
Geiger counters have various talents to detect and measure radiation. Many Geiger counters use peripheral wands that connect to the primary machine to measure particular varieties of radiation. Geiger-Mueller tubes are unable to inform the distinction between radiation occasions, so attachments or totally different mode settings are sometimes used to isolate radiation sorts.
Counting or dosing radiation is much less useful in the event you don’t know the kind of radiation. Studying the kind of radiation may also make it easier to determine the radiating isotope. This helps HAZMAT (Hazardous Materials) responders monitor down the supply of the radiation and even neutralize or include it if attainable.
Pancake probes, wands with a small round ‘pancake’ on the top with a specialised mesh, are usually used to detect giant areas.
Home windows are used on probes to scale back radiation detected by merely shielding out radiation you don’t want to detect. A small skinny mica sheet can slide over a probe to get rid of Alpha particle detection. A thick metal door is used to swing over some probes to get rid of beta particle detection, leaving simply gamma detection capabilities. We used all of those with the Victoreen detector within the navy and whereas they are often correct, it was a bit cumbersome to determine at first.
Most probes are utilized in navy and laboratory settings when you find yourself attempting to know radiation. Basic radiation readings might be higher for prepping and survival use since they extra merely present counts and dosages of mixed radiation. Accuracy remains to be vital for these, though they don’t seem to be in a laboratory setting. If you sacrifice accuracy, you’re often hurting your capability to measure background dose- which is usually on the decrease finish of the dimensions.
The detection ranges for the Geiger counters we advise are:
GQ GMC-300S: 0.01 µSv/h to 99 Sv/hr – low sufficient for background readings and excessive sufficient to trace a deadly radiation dose in 2 minutes.GQ GMC-320 Plus: 0.01 µSv/h to 99 Sv/hr – identical vary because the cheaper mannequin aboveNUKAlert: 1 mSv/hr to 50 Sv/hr – It takes quite a bit to get this one going, and whether it is maxed out, you have got lower than 5 minutes till you’ve absorbed a deadly dose.
We transformed a few of these from MeV, Roentgen, rad, rem, and so forth. to Sievert items, the usual worldwide (SI) measurement of dose.
Use a Geiger Counter
Radiation is throughout us. It comes from the Earth and comes from space- there is no such thing as a escaping it and unattainable to stop. Fortunately, most radiation is innocent and simply part of life. Dangerous radiation is absorbed in sufficiently small doses that it not often has any results. If you’re uncovered to an excessive amount of, it may be problematic. This is the reason individuals are restricted to the variety of X-rays they are often uncovered to.
How do you detect one thing that’s already surrounding you? You set a baseline and measure the distinction. Baseline measurements of radiation are known as ‘background radiation’ ranges. If you first flip in your Geiger counter, you’ll most likely have a studying. Don’t panic- that’s most likely the background radiation degree for the place you’re.
Anybody who owns a Geiger counter ought to map background radiation ranges for areas of their dwelling if they’ve time. This fashion, you possibly can inform when there’s a vital improve in publicity that places you and your loved ones in danger. It additionally allows you to turn into conversant in the gear and discover ways to function your particular mannequin.
This superb chart reveals how radiation dose compares to the Sieverts we’re naturally (and unnaturally) uncovered to:
Who Wants a Geiger Counter?
Ionizing radiation has the flexibility to break residing tissue shortly and over lengthy sustained intervals. Excessive publicity charges may cause radiation burns on the pores and skin and bodily membranes, cell harm, and loss of life. Excessive dosage accumulation may cause those self same results but in addition radiation illness and most cancers. There is no such thing as a strategy to construct a tolerance or immunity to radiation because it straight impacts your cells.
Radiation occasions are unbelievable however not unusual. Hiroshima, Nagasaki, Chernobyl, Three Mile Island, and Fukushima have all demonstrated the uncooked energy and lasting results radiation can have on big areas.
Regardless of the decrease probability of a radiation catastrophe, the influence of one among these disasters might be devastating. There is no such thing as a substitute for the gear wanted to detect and shield. A small funding in a Geiger counter detector mixed with protecting masks may also help you survive a radioactive occasion.
A Geiger counter is likely one of the basis items of a radiation detection package. These are often specialised kits to be thought of based mostly in your proximity to high-threat areas:
Fortunately, developments have decreased the majority and elevated the sturdiness and ease of use of Geiger counters. Because of this they are often included in lots of varieties of moveable kits, together with:
