Ambient radiation
µSv/h
Nearest live sensor appears once a location is set.
Typical outdoor background is roughly 0.05 to 0.3 µSv/h, depending on geology and altitude. Counts per minute are converted with a typical tube factor, so treat the value as approximate. Sensor data comes from Safecast and is a snapshot of unknown age.
