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.

Teaching goals: 

  • To learn about radionuclide generators,
  • working with short half lives,
  • getting more training in handling radioactive material,
  • learing about ion-exchange collumns.
