Which are the technical characteristics that should be taken into consideration in order to make a good choice of these stations? Do you know a good companies that have a reputation in these field? According to your experience what is the best way to communicate with this type of network?
2025-03-19 10:34As I interpret your question there will be 20 stations that have real-time gamma radiation measurements. That is the correct (and most cost effective) approach.
In addition to that, there will be a few stations that have alpha and beta radiation measurements. Presumably, that will come from air filter sample measurements. Those results will be gross alpha and gross beta, which will not tell you the isotopic identity of the radioisotope. This is as it should be.
Ordinarily, these samples would not be subjected to additional analysis by isotopic analysis for the beta emitting radionuclide or Alpha emitting radionuclide due to the expense. However, if there was an elevated gamma result, it would give an indication that there was something present and to help justify the additional analytical expense of actual alpha/beta isotopic. The air samples themselves can be saved for re-analysis at any time in the near future if justified by anomalous gamma data results that may occur if something out of the ordinary occurs somewhere that you might detect.
The elevated gross gamma will "trigger and guide" whatever investigation that follows.
I cannot recommend any specific vendors that might be available to supply your requirements. There are several out there and they are all competent. The best design for the gross gamma measuring system was that that the Germans showed the RMCC group, that was based on high and low level gamma measuring Geiger Mueller detectors.
