This one from Barcelona is interesting because the ionizing radiation measurements are taken on par with EMF measures, and the EMF seems to be relatively low, so the gamma rays measured (0,4 Roentgen/hour) would apparently not be a wrong metering influenced by the EMF.

Anyway, as 0,4 Roentgen/hour is too darn high to be survivable, I am becoming more confident in the idea that these meters are being subject to some kind of environmental influence that makes them provide falsely high radiation readings.

I have suggested to the makers of these videos to get the CDV-715 inside a Faraday Cage to be sure that the meters are not being played by the EMF, so far, none seems to have heard the message, but I hope someone does sooner or later:
