The radiation meter that started out as an experiment with a matching, short article in the June 2011 edition evolved gradually into a project that met with great interest with our readers. Designer Burkhard Kainka assisted by Elektor Lab worker
The radiation meter is based on a phototransistor rather than the far more expensive and elusive Geiger tube. Alpha, beta and gamma radiation can be detected with due care exercised in the interpretation of what appears on the LCD readout and a basic knowledge of physics and the test method. Sensor screening is critical to correct operation of the meter and in a follow-up article in the January 2012 edition a number of methods are explained to get the measurements right.
The kit now launched contains all parts to build the Elektor radiation meter, including the programmed microcontroller and LCD.
