Semiconductor radioactivity detector: part 3

Saturday, May 4th, 2019

Robert Gawron has made a new version of his radioactivity detector project and wrote a post on his blog detailing its assembly: In this post I will present a new hardware version of my sensor, older versions are described in part I and part II. In comparison to the previous...

Semiconductor radioactivity detector – part 2

Tuesday, February 19th, 2019

Robert Gawron has been working on a radioactivity detector, that is available on GitHub: There are many ways to measure radioactivity level, semiconductor detectors sense interactions between ionizing radiation and p-n junction. Because in hobbyist area most popular are Geiger-Muller based detectors (in short: not a semiconductor but lamp based...

Radioactivity detection using very simple ionization chamber and a single J-FET transistor

Thursday, December 29th, 2016

Robert Gawron writes: Today I will show a very simple ionization chamber that can detect radioactivity. I was able to detect with it ionizing radiation from a smoke detector (Am241 isotope). It's also immune to electromagnetic interference (EMI) due to a good shielding. This device doesn't explicitly use any power...

Semiconductor radioactivity detector

Monday, December 12th, 2016

Robert Gawron has been working on a semiconductor radioactivity detector project: Currently I'm trying to make a working version of a radioactivity detector that uses semiconductor as a sensor. It's a different approach than Geiger-Muller detectors, more complicated, but also much more interesting. While Geiger-Muller counters can only provide information...
