Dosimeters-radiometers: reviews. Principle of operation of dosimeters and radiometers

Dosimeters-radiometers are multifunctional devices that are designed to determine gamma radiation. In this case, the device determines the equivalent dose. Some models are capable of measuring neutron radiation. Dosimeters are used primarily in the nuclear industry. However, there are many household modifications on the market.

Simple model device

The main element of any dosimeter is considered to be a counter. The specified component is operated by a blocking generator. The devices also use a voltage multiplier.

Batteries are most often installed in a small capacity. Even dosimeters have a resonator and a modulator, which are located near the compact microcontroller.

Principle of operation of the device

The principle of the dosimeters and radiometers is based on the distortion of the limiting frequency of gamma-radiation. X-ray particles are directly captured by a counter. Then the signal is transmitted to the blocking generator. In order for the resonator to be activated, a converter is required. The single-vibrator in this case provides high sensitivity of the device.

The resonator, in turn, is responsible for the transmission rate of the signal. On the microcontroller, the gamma radiation data is passed through the modulator. Then they are immediately displayed on the display. Directly the voltage to the microcontroller is fed through the battery.
