Detection and measurement of radiation

Aims

To teach the students basic knowledge on interaction processes of radiation with matter as a basis for radiation detection, basic instrumentation in radiation detection, detector types and formation of electric pulses in them, interpretation of various spectra, energy resolution, energy and efficiency calibrations. Since ICP-MS is becoming a standard method for the measurement of many radionuclides basics on mass spectrometric measurement of radionuclides should also be at least shortly covered.
