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. More details about SS05 are available at http://optivelox.50webs.com/DL_en/ss0x.htm

Comments on RadMeter for Android

★★★★★ Balogh Szabolcs · Jul 6, 2021

Works great with the Chinese kit and sbm20 tube.

★★★★★ Jako Schonken · Mar 11, 2016

Jakes Coupled it with a radiation meter built by atomic.dave with a russian made SBT-9 geiger tube and it worked perfectly.

★★★★★ A Google user · Aug 6, 2017

App works with the Geiger counters that I have been making. You MUST HAVE AN EXTERNAL DEVICE for this app to work. Those who just run the app and stick their phone in the toilet or near the dog, get a high reading and claim the app is defective, are leaving misleading, ignorant reviews. I can not say if the calibration is accurate. I have nothing to compare/calibrate with and have only been experimenting with GM tubes for a few weeks now. But, it does measure and display CPM. Background radiation does appear to compare with what information I have found online for my area when I use SBM20 and SBT11 GM tubes. Using app with a Samsung Galaxy S5. The audio in this phone appears to be marginal for this use, but it seems to be OK. I find that slow CPM rates show as smaller pulses on the app's graph. Pulse height appears to increase with faster CPM rates. I am assuming this is my phone since I do not see this difference when looking at the pulses with an oscilloscope. Once the pulse height measurement is calibrated in the app, CPM measurements appear to work. Thank you for making this app!

★★★★★ Jeremy Caba · Jul 15, 2016

It worked after I put it next to a radioactive device, and it works with the radioactive device in the smoke detector

★★☆☆☆ A Google User · Sep 1, 2015

I just got a Smart Geiger FSG-001 today and can't find out which model it is in this app so it's not working. The device does work in its own app but it doesn't have a graph and this does, so I'm trying to get it working here. What model should I set it at?

★☆☆☆☆ The Wide Open Life · Jul 24, 2016

don't see how there is 100msv in my toilet the closest accident is marbling 600+ Kms away - iv it were that bad I'd be dead already - your phone can't detect radiation if it does not have a Geiger counter built in

★☆☆☆☆ Edeline Widjaja · Jul 6, 2019

It says my house and the city of Jakarta, Indonesia was over radiated while it's not!
