I have unit 8200007B and high radiation values at low temperatures.
it first appeared last winter and now it is starting again 🙁
(did not investigate it further, perhaps some component is malfuntioning at low temperature, unit is mounted outdoors)
hey, I was just curious about radiation maps and found these (staggering) measures. I found these remarks after having searched for a while. I was 5 min. away from contacting the Fanc, and they are quite serious about these things… Could you contact the owner to ask if he could get the device offline, or at least get it checked? Otherwise it brings the whole credibility of uRADMonitor down. Cheers.
