*The material used to detect beta particles inherently captures the occasional gamma hit. The material is thin to primarily stop betas, but statistically gamma radiation can be stopped as well, it is just significantly less likely. This is true of all beta scintillation material, and also in the inverse with gamma-sensitive material if it is not properly beta-blocked. The AB Lite and AB+ will experience the occasional gamma that reads to our software as beta. The AB+G utilizes the separate and properly blocked gamma crystal to separate out beta from gamma, hence the complete separation.
**We originally used BGO as the scintillation crystal in the AB+G, but that was before sanctions restricted the flow of this material into the US. As of Dec 2025, we have not had an encouraging resolution to this supply issue, so we are moving forward with a larger CsI(TI) crystal to provide both better sensitivity and resolution.
