Revision as of 23:34, 18 April 2025
Some quick recommendations / popular equipment:
- GQ
- Ex: GQ GMC-300S
- I'm not as familiar with these but price start quite low
- 2025-04-18: $62, link
- MightyOhm w/ SBM-20
- Entry level open source kit
- 2025-04-18: $120 on Amazon including SBM-20, link
- Radiacode 102
- Very popular portable / compact gamma spectrometer
- 2025-03-18: $250 on amazon, link
- Ludlum Model 3 Geiger counter
- The US nuclear industry standard Geiger counter / survey meter
- 2025: About $400 used on eBay (say wand or LND 723 tube)
- Gamma Spectacular
- If you want to interface to a more specialized gamma spectrometer detector
- Neutron detector
- Some Russian He-3 tubes work ok but there aren't any great standard options
- McMaster: I have a Ludlum Model 15 + some Eberline "sea mines
- They also tend to be difficult to test without specialized equipment / sources (working fusor, Po, etc)
Honorable mentions:
- Civil Defense Geiger counters: there are a lot of these. But generally best to transfer the detector to more modern electronics (ex: MightyOhm)
- ICX Identifinder: a community of us exists. In theory better / more industrial than Radioacode + some have neutron detector

MyGeiger ver.2.00
400 or 500 V depending on switch setting. Supported tubes:
* PCB mount: STS-5, SBM-20, J305 * External: LND-712, LND-7317, SBT-9, SI-29BG, etc * I use SBM-20
I have one from Atomic Dave and two bare units.
