Radiacode 103 vs GQ GMC-600 Plus CPM Radiation Test Pentax SMC Takumar 55mm f1.8 Vintage Lens. Comparing the new Radiacode 103 scintillation detector to the GQ GMC-600+ Plus Geiger Counter. We see the CPMs of radiation that is coming from an old Pentax SMC Takumar 55mm f1.8 vintage camera lens. The rear element has Thorium in the glass. It is only mildly radioactive and primarily emits alpha radiation (not gamma radiation) which has trouble even penetrating human skin.
