Principle
The radiation emitted during the decay of the 137Cs isotope is
measured with a scintillation detector and the energyspectrum
determined with a pulse height analyzer. The spectrum contains
fractions due to a gamma-transition and fractions originating from
a characteristic X-ray radiation. The areas of the fractions in
question are determined and the conversion factor obtained from
them.
Tasks
- Measurement of the g-spectrum of 137Cs using a
scintillation detector.
- Determination of the conversion factor of the 137mBa excited
nucleus.
