====== Pb-210 measurement by proportional counting ====== In this quest you will have to measure source with separated Pb-210 by proportional counting. After end of measurements you have to write down results to be able perform final calculations of Pb-210 activity in water. How this is performed in real lab you can preview [[http://videolectures.net/meet-cinch_modul32_po_pb_210_pb_measurement/|here]].
