Antiparticles and Geiger counters talk by Chris
One of our esteemed and regular members Chris gave an interesting talk on Antiparticles and geiger counters at EMF Camp 2018 . He built his own geiger counter and you can find his code on github here . Geiger counters are interesting and surprisingly useful devices, and you can build one for less than the price of a video game. They can monitor background radiation levels, check household items such as smoke alarms and gas mantles, and provide information about medical treatments. I designed and built my own unit having been diagnosed with cancer in 2017, and it has provided some fascinating insights. This talk describes the design and construction of a simple Geiger counter with an OLED display and a recording facility, and illustrates some of the science behind medical procedures involving radiation, such as PET scans (Positron Emission Tomography) and radiotherapy.
