Because of all the bullshit surrounding the Ukrainian nuclear reactors, I've been keeping an eye on my Geiger counter.

The normal background radiation in this area is 11 us/hr, that's eleven microsieverts per hour, or about one banana daily equivalent (the amount of radiation you get in a day being equal to that which you get from eating a banana).

However, the last two days have been an unusually low 8 us/hr or eight microsieverts per hour. I have no explanation or idea for what could LOWER background radiation.
