Author's NotesYour smartphone becomes a professional Geiger counter!


This application turns your phone into a powerful Geiger meter. RadMeter supports the most common silicon and Geiger tube sensors (SS05, BPW34, SBM-20, SBT10, STS-5, SI-29BG, LND712...), you can also define a custom sensor and add it to the internal database. The app supports measurements of dose rate (uSv/h, uR/h, Gy/h), activity (Bq, Bq/cm2, net or gross), Radon gas (pCi/l, Bq/m3).

If GPS tracking option is enabled, radiation data will be automatically paired with GPS coordinates and a proper KML file will be generated. Measured data can be easily mapped by using Google Earth.

This app is a real working radiation meter provided you connect an external sensor SS05. If you don't plug any sensor, the app will use the internal mic of the phone just for demonstration purposes. As alternative you can use a standard Geiger tube with a proper connection interface. For more details about SS05 please see
