Learning Goals
- Understand mother-daughter relations and radioactive equilibrium
- Understand how a radio-nuclide generator works and how it is used
- Understand how radioactivity is "growing in"
- Separate uranium and thorium using a cation-exchanger
- Training in handling radioactive material and safety procedures
- Understand the principle of neutron activation
- Deconvolute a decay curve with two components
Theory
Experimental Procedure
- making the 234mPa radionuklide generator
- how to measure the half life of 234mPa
- determining the half life of 234mPa
Safety Aspects
- Chemical safety - nothing particulary dangerous, 2-M HCl and 0.1-M AgNO3 should of course be handled according to normal safety precations. DOWEX residues and waste should be collected and handled according to normal procedures.
- Rad. safety - very small amounts of uranyl nitrate is used, so rad. safety is mostly about regulations and not a real healt hazzard. Remember to collect the DOWEX from the ion-exchange collumns in separate containers as it is contaminated with 24-day 234Th (will be none-radioactive after one year).
