The radiation meter that started out as an experiment with an accompanying short article in the June 2011 edition of Elektor evolved gradually into a project that was 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. In a follow-up article in the January 2012 edition, a number of methods are explained to get the measurements right.
A kit of parts to build the Elektor radiation meter, including the programmed microcontroller and LCD is available now.
