Portugal radiation map: live radiation levels

5 online stations · updated 4 minutes ago

Right now, 5 uRADMonitor stations in Portugal report a median background dose rate of 0.140 µSv/h, with values between 0.120 and 0.150 µSv/h. Typical outdoor background radiation is between about 0.05 and 0.20 µSv/h. It depends on altitude and local geology, and it rises briefly during rain.

This is a live, real-time radiation map of Portugal. It shows measured background radiation, not a modelled fallout plume: every point is a real Geiger counter station reporting now. In a nuclear event, the same network is how a sustained rise above local background would show up across Portugal.

Radiation stations in Portugal

How these values are measured

Each station counts ionizing radiation events with a Geiger tube and reports counts per minute (CPM). The dose rate shown here is the average of the station's latest readings multiplied by a conversion factor specific to its tube. Values from different tubes are comparable in µSv/h, not in CPM.

Frequently asked questions

Is this a real-time radiation map of Portugal?

Yes. Every value comes from a uRADMonitor Geiger counter station in Portugal reporting live, updated continuously. There are 5 stations online right now.

Does it show nuclear radiation or fallout?

It shows the ambient dose rate from all ionising radiation, natural and artificial. It is not a modelled fallout map, but a real release would appear as a sustained rise above local background across the nearest stations, which is exactly what a distributed network is built to detect.

What is a normal radiation level in Portugal?

Outdoor background is typically between 0.05 and 0.20 µSv/h, depending on altitude and geology. The current Portugal median across online stations is 0.140 µSv/h.
