Live measurements from Odense, Denmark. Counts per minute, interval over 2 days.
It is installed in Odense on the island of Funen in Denmark. It has been connected to the network since May 03, 2016.
Measuring background radiation with 22 CPM, the standard deviation is 3 times the square root of the count, which makes the normal range to be between 8 to 36. There should be no cause to alarm at values under 100 CPM.
This uRADMonitor is a network connected monitoring station, it is a uRADMonitor KIT1 that I bought from the initial kickstarter campaign. This capability is delivered by a digital dosimeter constructed around the highly sensitive Geiger Muller tube SBM20U. It is now a commercial product that you can buy here: https://www.uradmonitor.com/products/#2. But Radu has also released it as a full open source project that can be found here: https://github.com/radhoo/uradmonitor_kit1
It is part of the uRADMonitor network that is focused on continuous Environmental Radiation Surveillance. The system is developed by Radu Motisan from Romania.
