When you run the app, you will see a map of the world, with a number of circles.
Each circle with a number indicates the location of one sensor. Readings are approximately in uR/hr.
The App requires access to the internet.
If you do not see the circles, then it is likely that your internet connection has a problem.
Fix that, then launch the app again.
You can scroll and zoom in and out to see the various site.
Note that these are generally run by individuals, and not all readings may be accurate. Do not panic because you see a high reading. Someone could be getting invalid readings.
Treat this for information purposes only, do not make safety decisions based upon it.
