چکیده انگلیسی
The results of alpha spectrometric measurements of the activity of 222Rn daughters dissolved in liquefied nitrogen are presented. A direct detection method of ionized alpha-emitters from the 222Rn decay chain (214Po and 218Po) in a cryogenic liquid in the presence of an external electric field is shown. Properties of the radioactive ions are derived from a proposed model of ion production and transport in the cryogenic liquid. Ionic life-time of the ions was found to be on the order of 10Â s in liquid nitrogen (4.0 purity class). The presence of positive and negative ions was observed.
