Protect yourself and your family from concentrated radiation, industrial accidents and nuclear disasters with the ultra-compact MIRA Safety Geiger-1 Dosimeter, handheld geiger counter.

In deciding which Geiger counter model to purchase, we recommend that you first decide between these two basic types of construction:. Pocket Models Probe Models. What is the difference between a Pocket or Handheld Model, versus a Probe model? The heart or sensor of a Geiger counter is its Geiger-Mueller tube, and in a Pocket or Handheld Geiger counter, that GM tube is built right into the case. In a Geiger counter with an external probe, the GM tube is relocated to the end of the wand-style probe itself, attached by a cable to the base unit. See the pictures above:. Why choose a Pocket or Handheld model over a model with an External Probe?

It is widely used in applications such as radiation dosimetry , radiological protection , experimental physics and the nuclear industry. Since then, it has been very popular due to its robust sensing element and relatively low cost. However, there are limitations in measuring high radiation rates and the energy of incident radiation. The tube briefly conducts electrical charge when high energy particles or gamma radiation make the gas conductive by ionization. The ionization is considerably amplified within the tube by the Townsend discharge effect to produce an easily measured detection pulse, which is fed to the processing and display electronics. This large pulse from the tube makes the Geiger counter relatively cheap to manufacture, as the subsequent electronics are greatly simplified. This voltage must be carefully selected, as too high a voltage will allow for continuous discharge, damaging the instrument and invalidating the results. Conversely, too low a voltage will result in an electric field that is too weak to generate a current pulse. There are two types of detected radiation readout: counts and radiation dose. The readout can be analog or digital, and modern instruments offer serial communications with a host computer or network.

Wide applications, can be used in the home environment, daily necessities, mineral rocks, decorated stone and other radioactive detection.

While some exposure to radiation is natural, higher concentrations can be the result of poorly shielded electronic equipment, X-rays, CT scans, or even air travel. Beyond the substantial threat of nuclear meltdowns, disasters, and fallout, this excess background radiation can add up over the years and contribute to serious health issues. Only slightly larger than a ballpoint pen, the Geiger-2 is a full-featured handheld dosimeter that offers the same reliability as a professional-grade Geiger counter at a fraction of the price and without the bulk. Unlike traditional analog Geiger counters, the Geiger-2 is fully digital with various extremely useful features and modes.

This is an updated review guide on the best Geiger counter. Our first review roundup was several years ago and we will continue to update as new products are released and as new radiation detection equipment becomes available. 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. Demand in the industrial sector drives down the costs of Geiger counters for everyone. This is good news for emergency responders, preppers, and survivalists since it keeps the specialty tool from breaking our budget. We have researched, tested, and identified the best overall Geiger counter, as well as options for every day and those on a budget. We will show you how we got to our conclusions and share some info on Geiger counters along the way. A laboratory-grade tool that is durable enough to use for prepping and survival.

We recommend these products based on an intensive research process that's designed to cut through the noise and find the top products in this space. Guided by experts, we spend hours looking into the factors that matter, to bring you these selections. Simply put, a Geiger counter is used to detect radiation. With a Geiger counter, you can keep tabs on radiation in your food, water, and home. It is a necessity if you live near a nuclear reactor, and rockhounds or those interested in science will find any number of fun ways to use one.

We recommend doing this only with the help of a professional. Not being familiar with these devices, does it need to be calibrated at all, and does it have a functional life span? However, to facilitate more localised measurements such as "surface dose", the position of the tube in the enclosure is sometimes indicated by targets on the enclosure so an accurate measurement can be made with the tube at the correct orientation and a known distance from the surface. Geiger and W. Offers the same user-adjustable audible alert as in the Radalert Best value for the money in a traditional analog metered pocket model. There is usually an option to produce audible clicks representing the number of ionization events detected. Geiger counters with external probes offer these advantages, which may or may not be necessary for your application:. Best value for the money in an all around digital pocket model. Wide applications, can be used in the home environment, daily necessities, mineral rocks, decorated stone and other radioactive detection. However, there are limitations in measuring high radiation rates and the energy of incident radiation. Asked for replacement and told to file warranty claim and make a video of the unit not working.

Protect yourself and your family from concentrated radiation, industrial accidents and nuclear disasters with the ultra-compact MIRA Safety Geiger-1 Dosimeter. Or photo of it. For general area monitoring and in most instances where specific objects are checked for radioactivity, a Pocket or Handheld Geiger counter is usually sufficient. This is the distinctive sound associated with handheld or portable Geiger counters. United States. Still waiting on the refund. Bought some test items and yep, it works. Inspector Alert - From the Inspector line, among the most sensitive pocket Geiger counters available, a very popular unit, and perhaps the best hand-held unit ever. Works very well, accurate, fast response and the price is right. Onboard 2.
