When testing building materials in the renovation of factories ... the radiation data logger naturally also does its job. Two device versions are available online: the radiation meter in the standard version as model GS1 or the same meter but with acoustic signaling (ticker) as model GS2. The measured values of the radiation can be stored in the radiation meter itself and transferred to a computer and evaluated using the data kit (software and data cable) included in the scope of delivery. A measuring device of this series is intended for stationary use. It's the Gamma Scout Online (GS-3). This radiometer continuously sends measurement data to the PC or laptop (pulse transmission from the device to the PC every 10 / 30 or 60 seconds).
What is radioactivity?
Antoine-Henri Becquerel discovered at the end of the 19th century that uranium compounds emit invisible rays spontaneously, i.e. without external influence.
For example, the decay of radium emitting alpha radiation. The unstable nucleus of the radioactive isotope of radium (consisting of 88 protons and 138 neutrons) constantly strives to transition to a more stable state. Therefore, the radium nucleus emits a so-called alpha particle, equivalent to a helium nucleus, consisting of 2 protons and 2 neutrons. This is alpha radiation.
Which units of measurement are common in radiation protection?
We have no sensory organ to perceive the ionizing radiation. Measuring devices are required to detect radiation, and knowledge of the type and energy of radiation and the behavior of radionuclides in the body is required to assess the effects of radiation. For example, the activity measurement alone says nothing about the biological effect or the danger of the radiation.
You can find further general information on radiation measurement and radiation protection from the International Commission on Radiological Protection (ICRP) or the Society for Radiological Protection (SRP).
The supplied software is used to transfer the radiation readings stored in the radiation meter and evaluate them on the PC. However, the data can also be transferred and evaluated in other spreadsheet programs such as Microsoft Excel.
