RadMeter

Turn your Android phone into a radiation detection meter with RadMeter, the professional-grade app that transforms your device into a working Geiger counter when paired with external sensors.

RadMeter supports the most common silicon and Geiger tube sensors including SS05, BPW34, SBM-20, SBT10, STS-5, SI-29BG, and LND712 models. You can also define custom sensors and add them to the internal database for maximum flexibility. Whether you're conducting environmental surveys, monitoring radiation levels, or performing scientific research, this app delivers real-time measurements with professional accuracy.

Measure radiation across multiple units and scales. The app supports dose rate measurements in microsieverts per hour (uSv/h), microroentgens per hour (uR/h), and gray per hour (Gy/h). For activity measurements, choose between becquerels (Bq), becquerels per square centimeter (Bq/cm²), and net or gross readings. Radon gas detection is available in picocuries per liter (pCi/l) and becquerels per cubic meter (Bq/m³). Additional measurement modes include counts per second (CPS) and counts per minute (CPM), with adjustable detector thresholds to fine-tune sensitivity.

GPS tracking integration pairs radiation data automatically with geographic coordinates, generating KML files that map directly into Google Earth for spatial analysis. This feature is invaluable for contamination mapping, environmental assessment, and comprehensive data visualization. Real-time graphs display measurements with pan and zoom functions, supporting both Log10 and Log2 radiation scales for different analytical needs. The app automatically evaluates measurement error, giving you confidence in data accuracy.

Rad safety features include customizable radiation alarms that alert you to unsafe levels. Save screenshots and measurement data to the internal archive, then easily attach them to emails for reporting or collaboration. Export your complete datasets in CSV format for spreadsheet analysis or KML format for geographic mapping. A comprehensive user manual is built into the app, and RadMeter supports multiple languages including English, Spanish, German, French, Italian, Korean, and Russian.

Note: This is the trial version with some functions limited. For the full RadMeter Pro experience and additional capabilities, contact the developer. Without an external sensor connected, the app uses your phone's internal microphone for demonstration purposes only—a proper sensor connection is required for actual radiation measurements.
