To measure the level of radiation, a special device is used that can limit us from invisible danger – a dosimeter. Depending on the measurement conditions and requirements for the quality of the device, there are various modifications of this device. The main component of the dosimeter is a built-in (sometimes connected) Geiger-Müller counter, which counts the number of radiation particles passing through the chamber of the device. There is a special counter on the dosimeter that indicates the level of radiation and its change.

Types of dosimeters
There is a certain classification of dosimeters, based on which it becomes clear that the features of each individual device are designed for a certain field of human activity.
- Professional. In addition to measuring radiation in free space, this device allows you to measure the level of radiation in objects, liquids, gases, etc. In the varieties of the device, it is possible to measure the level of neutrons, protons, etc.
- Household. Comparatively cheap dosimeters of small size, designed for personal use in domestic conditions. Due to the low price, the measurement accuracy of this type of device is slightly lower, but it still allows you to accurately determine the level of radiation dangerous to humans. Most often, this dosimeter is used to check the radiation level of food, building materials, home furnishings, etc.
- Individual. It allows you to determine the accumulated radiation dose of a person. It is often used in tandem with another type of dosimeter.
- Military. Compared to the others, it has a reinforced hull, and is equipped to work in the aftermath of various explosions, including nuclear ones. It is most often used in the work of sappers.
Where can I buy a dosimeter
Easiest to buy dosimeter-radiometerby ordering it via the Internet, for example, in the electronics store "Your Health", or at the nearest radio market.
Why buy a dosimeter
A household dosimeter is an inexpensive device that can preserve your health at the most unexpected moment. It is wise to have a compact dosimeter in your arsenal, with which you can check products or objects that cause you any doubts or concerns. A conventional dosimeter measures the radiation level for 45 seconds, and then we will report that the normal radiation level is exceeded. The most accurate readings can be achieved by taking three measurements at a specific location. A signal for the disposal of an item is an excess of the background by 1-2 micro-roentgens per hour.
