Rating of the best dosimeters for 2020

The dosimeter is a device with light or sound alarm, equipped with a display, which is used to count the measurements that characterize the background radiation. Overview have compiled the best instruments for 2020 measuring various operating quantities and their power. The dosimeter can be of narrow or wide purpose. Popular models are of everyday value, which will be discussed later.

Dosimeter classification: principle of operation and purpose

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

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

• Gas discharge ionizing radiation;
• Scintillation;
• Semiconductor;
• Diamond-based devices;
• Photodiode;
• Integrating - an individual dosimeter. It has several subtypes: photographic film, chamber ionization, thermoluminescent, track, electret and radiophotoluminescent

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

The source of radiation substances can be hidden everywhere: air, water, food, materials, etc. Recently, special devices have been in great demand, which make it possible 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 decoding.

Table - "Radiation level, 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 mankind, the ingress of radiation is carried out in two ways: internal - through food, for example, and external - through the air. You can protect yourself from the second option, but the first option is a controversial issue.

A modern home 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 - they measure more than one radiation.
• For health (the field of medicine), "lung counters" 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 radiation of gases and aerosols (they 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 used to detect bad water. This even applies to reservoirs in which, for one reason or another, swimming may be prohibited.
• In trade, a dosimeter is used to check food, which shows the excess of nitrates. They can check things and other items purchased for the home.

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

How to choose a dosimeter? There are 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, which 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, products from AliExpress are popular for budget prices and good quality of goods. The only drawback of the trading platform is the long wait for the parcel and the possibility of mechanical damage during transportation.

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

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