This lab exercise was developed for the UiO KJM 5911 course. The students will prepare a ion-exchange collumn using DOWEX-50 ion-exchange material and extract 234Th from a 234U solution. The thorium sticks to the ion exchanger and 1.17-min 234Pa will grow inn. The column can be milked once every 12 min. The students use 234Pa samples to measure its half life.
Learning goals
- To learn about radionuclide generators,
- working with short half lives,
- getting more training in handling radioactive material,
- learing about ion-exchange collumns.
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).
