Radiation monitor Ludlum 12S meter?

For DETECTING the Ludlum12S is hard to beat, and is a good instrument for your application.?
I used a similar instrument to track down a defective industrial X-Ray machine at a factory in an industrial park.

The rays were so strong and non-directional they could be detected at a distance of about 1 mile, then only stopped because the terrain went over a hill.

Inside the industrial park, there was no directivity due to the strength, but the Ludlum still gave a reading (full scale all ranges). The rays literally filled the entire industrial park. Even when inside the offending factory, the Ludlum scintillator still gave readings just as it should. I reported the problem to the factory head and he shut down the machine. We saved some lives that day I have no doubt. When I reported the incident to the State Authorities, they said. OH THEM! We had trouble with THEM before.

The VALUE of those readings is not correct, so to MEASURE needs a different instrument (which I have) , but the 12S will DETECT, no problem.?

Same cannot be said of any actual Geiger Counter. GM sensors will shut off (saturate) in a high field. Go to ZERO in cheap meters, others like Ludlum monitor for that and turn on an alarm. In no case can a GC be used to measure beams.
