	Noticed that this host had gone yellow. Then looked at the trace and see that 24-hour cycle that was discussed before: Cheers, Al. ____________

	One more interesting is Spikes seem to be every day at approx 8:00 AM UTC

	Yes, after 5 'quiet' days, it's starting again. Would love to know what is causing this! Cheers, Al. ____________

	First it would be useful to know where your detector is located. For example, radon can have influence on this. Second, I see, that your dose rate values are ranging from 350 to 500 nanoSv/h (according to graph in "Message 1823") which is slightly bigger. Is it your normal background level? I would check the geologic map of your locality - there could be rocks with higher radioactive elements amount. Other possible source are building materials ...

	According to the map the sensor 5925 is located in the Cinema City Kinepolis and near the rail way. Can the spikes be caused by some radioactive goods transported by trains?

	hi, we discussed this with my colleague and according to him, those spikes take too long time to be caused by trains. Ok, I was also thinking about trains transporting something like coal with higher uranium amount but in such distance it could be not such high dose rates. We should take in account an hardware problem in the detector. It would be nice to have also measurements from another detector near this one...

	One more interesting is Spikes seem to be every day at approx 8:00 AM UTC And the weird spikes are back again. Nothing showing on the nearest sensors to this one. It would be great if the owner of the sensor could give some information ... Hint! Cheers, Al. ____________

	Would be nice if the owner of the detector could test it in another location to prove or exclude detector hardware error. This is strange.

	We have talked to the owner on IRC, the detector was exposed to sunlight and probably high temp caused these glitches.
