An alpha-spectrometer, consisting of a photodetector, a preamplifier, a pulse height analyser and a recording device for registration of the spectra is calibrated by means of an open alpha-emitter of known alpha energy (241Am). The energy spectrum of a radium source which is in equilibrium with its decay products, is recorded and evaluated. The alpha-energies found in this way are allocated to the corresponding nuclides of the radium decay series.
Tasks
The Alpha-spectrum of the 226Ra is recorded with multichannel analyzer.
The calibration spectrum of the open 241Am alpha-emitter is recorded at the same settings.
The alpha-energies corresponding to the individual peaks of the alphaspectrum of the radium are calculated and compared to the values in the literature.
