Rating of the best dosimeters for 2022

A dosimeter is a device with a light or sound alarm, equipped with a display on which measurements are taken that characterize the radiation background. Review compiled the best instruments for 2022, measuring various operating quantities and their power. The dosimeter can be narrow or wide purpose. Popular models are of domestic importance, which will be discussed later.

Classification of dosimeters: principle of operation and purpose

What dosimeters are and what they measure are the main questions for beginners faced with such a device. A large category is home appliances. In simple words, they measure the level of radiation, and, depending on their capabilities, last for various types.

Classification of dosimeters according to what type of detector is installed in them:

• Gas-discharge ionizing radiation;
• Scintillation;
• Semiconductor;
• Devices based on diamond;
• Photodiode;
• Integrating - an individual dosimeter. It has several subtypes: photographic film, camera ionization, thermoluminescent, track, electret and radio photoluminescent

Note. The household appliance became widespread after the accident at the Chernobyl nuclear power plant (1986). Up to this point, it was used in scientific and military fields of activity.

The source of radioactive substances can be hidden everywhere: air, water, food, materials, etc. Recently, special devices have been in great demand that allow you to determine dangerous areas for living and examine goods for damage by radioactive substances. They are called dosimeters. To understand how radiation affects the human body, the table shows the norms and their interpretation.

Table - "The level of radiation, an explanation of its meaning"

Dose:	Name:	Explanation:
2.4 mSv/year	background radiation	norm
1 sievert		dangerous changes in the blood
2 sievert		development of leukemia
3 sievert		provokes serious changes, subsequently can provoke a fatal outcome

For humanity, radiation enters in two ways: internally through food, for example, and externally through the air. You can protect yourself from the second option, but the first option is a moot point.

A home modern device can simultaneously measure several radiations in various substances (objects):

• For radiation, the soil is measured by gardeners, gardeners and agricultural organizations. In this case, it is better to use universal dosimeters - more than one radiation is measured.
• For health (medicine), "lung meters" are used, which are located on the lower floors of the premises. They are protected from background gamma and neutron radiation. Such systems measure and count the radioactive emissions from gases and aerosols (do not dissolve in human tissues) that a person inhales. Such substances can leave the lungs in a few days, months or years.
• In construction, such devices are used both indoors and outdoors so that the building is in an ecological place and is made of clean materials.
• The device is operated to detect bad water. This applies even to bodies of water in which, for one reason or another, swimming may be prohibited.
• In the field of trade, a dosimeter is used to check food products, which shows the excess of nitrates. They can check things and other items purchased for the home.

Tips for choosing: if you plan to purchase a meter in an apartment, then it is better to buy a professional one. It has a wide measuring range. A specialized dosimeter is suitable for a specific measurement of the background radiation.

How to choose a dosimeter? There are some selection criteria in this matter:

1. Purpose;
2. Technical properties;
3. The material from which the device is made;
4. Price segment;
5. Which company is better.

The main criterion when choosing a dosimeter, what you should immediately pay attention to is the measurement range: the higher the numerical indicator, the better. Modern devices can work independently, in conjunction with a personal computer or smartphone.

The easiest way to get these tools is to place an order in one of the virtual stores. According to buyers, goods from AliExpress are popular for budget prices and good quality goods. The only drawback of the trading platform is the long waiting time for the parcel and the possibility of mechanical damage during transportation.

Where to buy a radiation device, in fact, is not so important. The main thing is that the instruction in Russian is attached, and the capabilities of the dosimeter satisfy the needs of the buyer.

Buyer reviews, advice from sellers and recommendations from people who have purchased the same model as you would like to help avoid mistakes when choosing. The manufacturer plays an insignificant role in this matter.
