Pocket Geiger Counter Pro 1.40

The application under review allows iPhone users to utilize their device as a radiation detector, functioning similarly to a Geiger counter when paired with the Pocket Geiger Counter. Connecting the voice output of the Pocket Geiger Counter to the microphone input of the iPhone facilitates this usage.

Specifications:

• Sensor: PIN photodiode x8 (reverse biased and shielded)
• Detectable Radiations: Beta and Gamma radiation
• Measurement Range: 0.05 µSv/h to 10 mSv/h (calibrated using Cs-137), 0.01 cpm to 300,000 cpm
• Measuring Time: Approximately 5 minutes at a dose rate of 0.05 µSv/h
• Energy Response: 662 keV to 1333 keV

Software Features:

• uSv/h and counting error calculation
• CPM calculation
• Manual setting interface for time range and threshold (Pro version only)
• Oscilloscope functionality (Pro version only)
• Detection log visualization (Pro version only)
• Circuit diagram access (Pro version only)
• Data saving and logging options (Pro version only)
• Measurement data sharing with location information on a map (Pro version only)

Data Sent by the Application:

• Date and time
• Position (latitude, longitude)
• Measurement values (µSv/h, cpm)

The application explicitly does not collect personally identifiable information such as device IDs, ensuring users' privacy. Uploaded data remains confidential and is not made publicly available.

Notice:

Please be aware that increased battery consumption may occur during measurements, especially with GPS location tracking enabled. Prolonged background use of GPS can significantly diminish battery life.

Note: There is a commitment to developing an affordable smart radiation detector, particularly focused on regions like Fukushima, supported by a collaborative effort among volunteer engineers, designers, and scientists. Further information is available at Radiation Watch.
