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"
  • Training in handling radioactive material and safety procedures


Theory

Experimental

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).
