Preliminary study of the applicability of the thin gap method on alpha emitters

The thin gap method as an in-situ radiotracer technique is widely used. This study investigated the applicability of alpha emitters. PIPS and CsI alpha spectrometers were applied in a thin gap cell. A suitable 210Po source was prepared by spontaneous deposition, Mylar foil was used to simulate water...

Description
Summary:The thin gap method as an in-situ radiotracer technique is widely used. This study investigated the applicability of alpha emitters. PIPS and CsI alpha spectrometers were applied in a thin gap cell. A suitable 210Po source was prepared by spontaneous deposition, Mylar foil was used to simulate water. A maximum intensity decrement of 7% within 25μm was observed. Even though this method is suitable for the study of surface phenomena, further investigation is necessary e.g. into water and heat sensitivity. •A new radiotracer method for the measurement of alpha emitters is introduced.•The applicability of the method is verified.•A process for the preparation of pure 210Po isotope is introduced.
