Radiometer Alpha-Beta-Gamma SM-5-D |
|
|
This portable radiometer is for the measurement of Alpha and Beta superficial activity, as well as the dose of Gamma radiation on site. The radiometer is easy to use (prior knowledge of radiation is not required). Thanks to the ergonomic and strong case, the radiometer Alpha -Beta-Gamma SM-5-D is an eligible instrument for mobile use. By means of a fast verification you can obtain the average value of the current dose rate in 60 seconds. The radiometer Alpha-Beta-Gamma SM-5-D has an acoustic indicator of impulses; this means that it can obtain acoustically the period of disintegration. The radiometer SM-5-D that detects the Alpha-Beta-Gamma radiation is used for different applications, for example for protection of the environment, the construction sector, elimination of trash, recycling, etc. The radiometer is therefore very versatile and is a very useful tool to measure radioactivity. Here you will find a general overview of our radiometers / meters of radiation. In case you had any questions on the radiometer Alpha-Beta-Gamma SM-5-D, read the technical data or get in contact with us: |

What is radioactivity? |

What is the unit to measure radioactivity?
The human being does not have any sense to detect radiation. Meters are necessary to detect radiation. Furthermore, to interpret radiation values it is necessary to have prior knowledge on the type of radiation and energy, as well as on the behavior of radionuclides in the body. For example, the measurement of activity in itself does not say anything on the biological effect or the danger of radiation (to obtain detailed information of the units of measure follow the link above). |

of uranium emit invisible radiation spontaneously, without external influence. For example, the decomposition of radio emits alpha radiation. The unstable nucleus of the radioactive isotope (composed of 88 protons and 138 neutrons) constantly strives to move to a stable state. Therefore, the core of radio emits an alpha particle, synonymous with a helium nucleus consisting of two protons and two neutrons. This is known as alpha radiation. you will find a detailed explanation of radioactivity if you follow the top left link or click on the image to the right. |
