My geiger counter activity goes up when air conditioner is working. Never figured out why. This could be a good explanation.

  Is your interior AC unit or its ducting in a basement or crawlspace?

    It's interior. No ventilation. I guess it's ionizing the air and bringing radioactive dust particles to the whole room. The radiation level is still very low so I'm not worried.

  Does your AC include a negative ion generator for cleaning the air? I wonder if that could be affecting it?
  • dogben 3y ago
    I don't think it has negative ion generator. I guess the fan itself can generate ions, that's why aircraft have static dischargers.
