1. Understand mother-daughter relations and radioactive equilibrium
2. Understand how a radio-nuclide generator works and how it is used
3. Understand how radioactivity is "growing in"
4. Training in handling radioactive material and safety procedures

The task in this Laboratory Exercise is to record a disintegration curve of ^234mPa and from this curve determine the half-life of the nuclide.
The ^234mPa radionuclide is obtained from a generator system consisting of an ion exchanger column with fixed ²³⁴Th where the daughter is milked by a liquid elution process.
The α particles from the produced ^234mPa-source is recorded by a GM-detector.
