Canada radiation map: live radiation levels

10 online stations · updated 2 seconds ago

Right now, 10 uRADMonitor stations in Canada report a median background dose rate of 0.115 µSv/h, with values between 0.077 and 0.230 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 Canada. 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 Canada.

Radiation stations in Canada

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 Canada?

Yes. Every value comes from a uRADMonitor Geiger counter station in Canada reporting live, updated continuously. There are 10 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 Canada?

Outdoor background is typically between 0.05 and 0.20 µSv/h, depending on altitude and geology. The current Canada median across online stations is 0.115 µSv/h.
