    Why is unit 8200007C measuring 86uSv/h? We’ve contacted the person by phone at the geographical location, but this person is unaware of the uRADMonitor network. Does anyone have more details?

    Hi Bram,

    Only Radu knows who bought that sensor, so he can inform them about the issue. That unit’s radiation sensor started acting up at the begining of September. There’s definitely something wrong…

    It would be a great idea to have the possibility to contact uradmonitor users anonymously via the device’s “history” window!

    Cheers,

    I messaged the owner but failed to get a reply so far. I suspect a technical issue, perhaps something related to the geiger tube.

    Definitely we need some better communication tools for the community.

    Will let you know as soon as I have news.

    It’s confirmed that the unit is broken. The ANVS (Dutch authority on nuclear safety and radiation protection) figured this out with Radu and the owner.

    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)

    Hello Luc,

    I can only think of some excess condensation taking place. Do you have access to the unit to check how it stands?

    Other than that, it can also be a tube failure, in which case I will need to service your unit.

    Thanks,
    Radu
