I met some great people today, and I also got a wonderful device for my ongoing experiments as a gift: The UT50 Scintillation probe, manufactured by SC ICPM SA Romania. It features a huge NaI(TL) crystal, with a diameter of 5.5cm and 5.5cm length. The photomultiplier is a British EMI9656KB and the entire device is encapsulated in an aluminum modular cylinder of no more than 24cm total length and 1270g…
The CDV-717 is a very high-range gamma radiation ionization chamber detecting instrument, manufactured by Victoreen back in 1964.
A digital dosimeter design that can be used with multiple geiger tubes, constructed around the atmega8 microcontroller and a 2×16 LCD. Equipped with a radio Bluetooth module for remote operation.
A story of making a DIY Digital Geiger counter circuit, that can be used with several tubes. Add an enc28j60 Ethernet module and use the data to create graphs available online!
