Geiger Counter is gas discharge device for automatically count the number of ionizing particles caught in it. It is a gas-filled capacitor which breaks when the span of an ionizing particle through the gas volume. Additional electronic circuit provides a power meter (typically at least 300), provides, if necessary, discharge quenching and counts the number of discharges through the meter. Geiger counters are divided into not self-extinguishing and self-extinguishing (does not require an external circuit discharge termination). Halogen self-quenching counters have the lowest supply voltage, excellent output parameters, and high enough speed, they proved to be particularly suitable for use as ionizing radiation sensors in household appliances radiation monitoring. Counters of this type of a named you can find on this site.
Cylindrical Geiger-Muller tube consists of a metal or metallized inside the glass tube, and a thin metal wire stretched on the cylinder axis. The thread serves as the anode, the tube - the cathode. The tube is filled with a rarefied gas, in most cases using inert gases - argon and neon. Between the cathode and the anode, a voltage of hundreds to thousands of volts, depending on the geometric dimensions of the electrode material and the gaseous medium inside the counter. In most cases, Geiger counters require voltage 400 V.
An important feature of the meter is its effectiveness. Not all the γ-photons that fall onto the counter, and the secondary electrons will be registered as acts of γ-rays interact with matter are relatively rare, and some of the secondary electrons is absorbed in the walls of the device, without reaching the gas volume.
The efficiency of detection of particles by the Geiger counter is different, depending on their nature. Charged particles (e.g., alpha and beta rays) cause discharge in the counter almost always, but some of them lost in the walls of the counter material. This is especially true for the alpha particles and the soft beta radiation. For recording in the counter make thin (2-7 microns for registering alpha radiation and 10-15 for soft beta-radiation) window of mica, aluminum, or beryllium foil or polymer film. The effectiveness of the counter for the X-ray and gamma-radiation depends on the thickness of the walls of the counter, their material and energy gamma radiation.
Widespread use of Geiger counter due to the high sensitivity, the ability to detect different types of radiation, the relative ease and low cost of installation.
When measuring the weak flow of ionizing radiation using the Geiger counter you must take into account its own background, which is present even in the thick lead shield. One reason for this spontaneous activity is a tough counter of space radiation, penetration without significantly weakening even after tens of centimeters of lead and consisting mainly of the muon. After every square centimeter of the surface of the earth flying an average of about one muon per minute, while the detection efficiency of Geiger practically equal to 100%. Another source of background - a radioactive "contamination" of the counter materials. In addition, a significant contribution to your own background gives spontaneous emission of electrons from the counter cathode.
However, almost all devices, except of specialized devices that are used for research purposes, have similar shortcomings. And, despite this, the Geiger counters is still actually the most accurate and affordable means of measuring radiation. With the help of devices placed on this page, you can always be confident in the safety of your home, family members and pets. If you own the property, like to travel or just want to be confident about yourself and loved ones, a Geiger counter - is one of the most necessary purchases. On the product page you can read a detailed description of each type of unit and learn about its specific advantages, as that may be:
- speed of measuring and data processing
- types of radiation measurement
- measuring range
- the type of dosimeter installed
- basic characteristics: size, weight, availability of display, etc.
- the type accumulator
- the ability to connect to PCs and mobile devices using Bluetooth
- types of radiation notifications: with the exception of standard cod it can be a different sound, vibration and LED-notification
You can find Geiger Counters on this page and choose one.
Geiger muller Counter dates as far back as the 1928 and has been an extremely useful tool in measuring radioactivity by detecting the ionizing particles present in a substance. The Geiger counter made for mobile devices works in a similar fashion by detecting radiation off the devices you place it by. The effectiveness of location of particles by the Geiger counter is extraordinary, contingent upon their temperament. Charged particles (e.g., alpha and beta beams) cause release in the counter quite often, however some of them lost in the dividers of the counter material. This is particularly valid for the alpha particles and the delicate beta radiation. For account in the counter make thin (2-7 microns for enlisting alpha radiation and 10-15 for delicate beta-radiation) window of mica, aluminum, or beryllium thwart or polymer film. The viability of the counter for the X-beam and gamma-radiation relies upon the thickness of the dividers of the counter, their material and vitality gamma radiation.
Round and hollow Geiger-Muller tube comprises of a metal or metallized inside the glass tube, and a thin metal wire extended on the barrel hub. The string fills in as the anode, the tube - the cathode. The tube is loaded up with a tenuous gas, much of the time utilizing dormant gases - argon and neon. Between the cathode and the anode, a voltage of hundreds to thousands of volts, contingent upon the geometric measurements of the terminal material and the vaporous medium inside the counter. By and large, Geiger counters require voltage 400 V.
You can find a couple of Geiger counter that you can use for yourself personally at home. The counter is a very versatile tool and its use can be noticed in a lot of areas. Some of the features of an Geiger counter include.
- speed of estimating and information preparing
- the capacity to interface with PCs and cell phones utilizing Bluetooth
- estimating range
- the kind of dosimeter introduced
- kinds of radiation warnings: except for standard cod it very well may be an alternate sound, vibration and LED-notice
- fundamental attributes: measure, weight, accessibility of presentation, and so on.
- the sort collector
- kinds of radiation estimation
These are some of the things you need to look out for when you want to make your next Geiger purchase. You can get a portable Geiger counter, the hand sized types or you could get a professional one. The whole point is to make sure you have a working tool with you. Anywhere you go to, you can now feel very confident measuring your radiation and being able to read the radiation counter. In any case, all gadgets, aside from of specific gadgets that are utilized for research purposes, have comparative weaknesses. Furthermore, regardless of this, the Geiger counters is still really the most precise and moderate methods for estimating radiation. With the assistance of gadgets set on this page, you can simply be certain about the wellbeing of your home, relatives and pets. On the off chance that you claim the property, as to head out or simply need to be sure about yourself and friends and family, a Geiger counter - is a standout amongst the most important buys.
