Please note: For reasons of privacy of the site owners, the exact positions of the measuring stations are rounded to an accuracy of 1 kilometre.

Hourly measured values Please note: Values may not be verified!

The figure "Hourly measured values" shows the hourly averaged values of the ambient dose rate in µSv/h over the last seven days (green line). The time series are updated every hour.

The times in the graphic are in Coordinated Universal Time (UTC). Central European Time (CET) valid in Germany corresponds to UTC plus one hour; Central European Summer Time (CEST) corresponds to UTC plus two hours - this means: a time of 00:00 a.m. in the graphic represents 01:00 a.m. in winter and 02:00 a.m. in our German time.

The blue line represents the precipitation at the site of this measuring station, determined by Germany's National Meteorological Service (DWD) with the help of weather radar.

Daily mean values

The figure "Daily mean values" shows the daily mean values of the ambient dose rate over the last 365 days.

Verification of the data

In order to distribute the data more rapidly, BfS does not verify the ambient dose rate data before it is published. Please note that unverified hourly mean values may be subject to technical errors that can easily be seen in the time curves while probes in the vicinity do not show any unusual values. Verification of the current data is performed in the morning before 10 a.m. Older data have been verified. Data that is obviously wrong will be marked in the time series and will not be represented here.

Natural variations in the ambient dose rate, e.g. due to rain or snow, and well-known sources of technical errors are explained in more detail under Interpretation of measurements.
