Tool description

This tool connects to a RadiaCode radiation detector straight from your browser using the Web Bluetooth API and shows its readings live. It reads the device about once a second and shows the current dose rate, count rate, highest dose rate of the session, accumulated dose, battery level and temperature.

Charts show the dose rate and count rate over the last minute, 5 minutes, 15 minutes or hour. The readings table keeps up to an hour of data with the error of each reading, and the events table lists what the device reports, such as alarms, dose resets and charging. Both tables export to CSV or JSON.

Features

  • Connects over Bluetooth without an app, driver or account
  • Live dose rate in µSv/h or µR/h, starting in the unit the device uses
  • Count rate in counts per second, with the statistical error of each reading
  • Peak dose rate, accumulated dose, battery level and temperature
  • Dose rate and count rate charts with a choice of time window
  • Readings and device events tables with CSV and JSON export
  • Pause and resume, with the records from a short pause filled in

How it works

After you pick the device in the browser's Bluetooth dialog, the tool runs the handshake of the RadiaCode protocol: it opens the data exchange, sets the device clock and checks the firmware. It then reads the device's data buffer on a timer. The buffer holds the records the device has made since the last read, so a short pause does not leave a gap: the records made in the meantime arrive when you resume.

The tool shows the dose rate in µSv/h or µR/h. Everything happens in your browser, and no readings are sent anywhere.

Tips

  • A RadiaCode accepts one Bluetooth connection at a time. Close the RadiaCode app on your phone or turn off its Bluetooth before connecting here.
  • Web Bluetooth works in Chrome, Edge and Opera on Windows, macOS, Linux, ChromeOS and Android. Firefox and Safari do not support it.
  • Firmware 4.8 or newer is needed. Update the device from the official app if the tool reports an older version.

This tool is not a safety instrument. Use the device itself and its alarms to judge radiation risks.
