How to choose the dosimeter

Household dosimeter-radiometer "Pine"

A dosimeter is a device to determine the effective dose of radiation, and ionizing radiation for a certain period of time. Sometimes by mistake dosimeter is called a radiometer is a device for measuring the activity of radionuclides in liquids, aerosols, and surfaces and other samples. Modification of the radiometer to measure the gamma-radiation is called roentgenstr. How to choose this product below.

step 1

Geiger (four tubes inside)

The radiation sensor. Sensors radiation dosimeters can be ionization chamber, scintillator, a Geiger counter, or semiconductor diodes. The ionization chamber is a gas sensor that measures the level of ionization of the gas in the working chamber. A scintillator is a substance that emits light when hit on him ionizing radiation. A Geiger counter (a more modern version of the Geiger-Muller) is a gas discharge device, calculating the pass-through ionizing radiation.

2 step

RADEX RD1503

The type of dosimeter. All dosimeters are divided into professional and consumer. First the majority of high-precision combined instruments (dosimeter-radiometer), measuring all types of radiation. Used mainly by professionals and by plant personnel and other dangerous objects. Personal dosimeters measure only gamma or beta radiation (sometimes both), have a smaller range of measurement and accuracy. They have small dimensions and weight. Some personal dosimeters do not even have a display, only the indicator and audible warning - these devices are referred to as radiation detectors

3 step

DOSIMETER SMG-2

Conclusion. The dosimeter may need you in several cases: for example, to check for any suspicious food, some areas of the radiation measurement on the ground, etc. In any case, such a device once useful to you, and can and will save your life. The optimal parameters for the price and quality are devices RADEX produced in Russia, for example RD1503 and RD1503+. Price 5200 rubles and 5800 rubles respectively. From foreign devices can be noted SMG -1 (6000 rubles) and SMG -2 (8000 rubles) made in Germany. Latest device reminiscent of mobile phone design and can be connected to PC to save the data.
