Unique Sell - Assembled unit of Gamma Viewer MCA ver.3.60 and photomultiplier sensor with tiny CsI(Tl) crystal.

MCA & CPS Survey Meter for amateur prospecting and simple gamma spectrometry.

Lifetime support and communicable developer!


The device is fully assembled multi-channel analyzer unit with internally installed photomultiplier / SiPM sensor and CsI(Tl) crystal ~1cm^3. Energy resolution ~9-10% at 662keV.

The MCA can be used as a simple gamma spectrometer for the energy range of 26keV-2000keV and as a survey scintillation meter for prospecting in range of 26keV-3000keV. Due to nature of the scintillator, it has plenty gamma sensitivity and fast reaction even for the small volume of 1cm^3 compared with an average Geiger tube. That's why the device is nice portable tool for searching radioactive contamination or hunting for a vintage radium clocks.

Gamma spectrometer has very basic performance, it made just for general impression of the gamma ray spectrum. Identify RIID menu is experimental programmed for Am-241, Cs-137 and Ra-226 isotopes only.
