Modern living conditions dictate the need to purchase certain devices that can timely determine the presence of harmful effects on the human body. Such devices include a dosimeter - a special device that allows you to measure the level of radiation in a particular place or object.

On sale today there are a large number of such equipment, people often seek to purchase them. These units are capable of taking measurements both outdoors and indoors. With their help, you can determine whether the products purchased on the market or other items are sources of radiation. Despite the fact that products of this type have been known for a long time, not all people know how to choose them correctly. It was for them that we decided to write our today's review of the best household radiation dosimeters of 2019. Here we will analyze in detail the useful qualities of specific devices, and also consider what dosimeters are and what points should be paid special attention to when buying them.

How to choose a home dosimeter?

The key element of the dosimeter is a special sensor, with which you can determine the degree of radioactive contamination, and do it in real time. From the performance of this part directly depends on how quickly the result and its error will be obtained. The sensors are of two types - cylindrical and end. The former looks like an elongated tube made in the form of a cylinder. The end ones are equipped with a special ionization chamber, and the working surface here is much larger.

Most modern instruments are capable of measuring alpha, beta and gamma radiation. They allow you to determine the dose rate received in a predetermined period of time, and in this case it should be borne in mind that radiation has the property to accumulate in organic tissues. There is also a natural background radiation coming directly from the ground, so measurements taken at ground level will be slightly higher than those taken at some height.

In general, household appliances are characterized by compact overall dimensions and reasonable cost. Be sure to pay attention to the limits of measurement. Typically, in devices designed for use at home, this parameter is in the range from 0.05 to 10 μZ / h. There are models that are equipped with both end and cylindrical sensors, which allows for the highest accuracy in measuring the level of radiation. A similar approach increases the sensitivity of the equipment.

The manufacturer also needs to pay attention - Chinese companies have not yet learned how to make dosimeters of acceptable quality with rare exceptions, but domestic companies produce reliable, durable high-precision devices. It is advisable to give preference to the most compact models, so that you can put them in your pocket if necessary. If the dosimeter is capable of operating on batteries or batteries, this will be an additional plus.Most users prefer designs equipped with a liquid crystal monochrome display, from which it is convenient to read data. As a rule, it is equipped with a backlight, so the necessary information can be found even in conditions of lack of natural light.

When choosing models for inclusion in our rating of the best household dosimeters, we mainly based on these indicators. However, user feedback and value for money were also taken into account. We tried to select not very expensive devices, so that each of our readers could choose the best model for themselves, both in cost and in functional content.

10 best dosimeters

10. RADEX RD1008

Domestic products can be used not only in domestic but also in industrial conditions. With it, you can calculate the level of radiation, find out how dense the flow of radioactive particles is, calculate the doses of gamma and beta radiation. The device can work even with the heaviest alpha particles, which are usually found in luminous paint, some types of crystal and so on. The principle of operation of this equipment is based on the use of two Geiger-Muller counters. The first of these is aimed at determining alpha and beta particles. The second responds exclusively to gamma radiation. The data that comes from these sensors to the central processor is processed using the most advanced mathematical algorithms, and the data is displayed on a liquid crystal display.

The device responds to radiation quite quickly - it will take 1 to 21 seconds to get the result, depending on how strong the dose comes to the sensor. Two people can use the device at once, and each of them can set the most convenient settings for themselves. The sensitivity of the equipment is significantly higher compared to devices of the previous generation. The product runs on ordinary finger batteries, the energy consumption is negligible, so the power sources will have to be changed about once a year.
