RobertGawron/SemiconductorRadioactivityDetector
Nuclear radiation sensor with photodiode as a detector. Photodiode doesn't require high voltages as GM tubes do. Smaller size makes better resolution. Side effect is electronic must be more sensitive.
RobertGawron/GammaSpectrometer
Device for quantitative analyze energy spectra of gamma-ray sources. Allows to study what radioactive isotopes in what quantities are present in measured sample.
