Sheets, C. Thompson] Ingrowth and decay of210Po on air filters used for gross alpha-determination can lead to errors in estimation of long-lived airborne radioactivity. Interferences are present to some degree in all samples and change with time, making the gross alpha-technique quantitatively invalid. However, since the degree of equilibrium between210Po and its parent210Pb can be calculated at any time after filter collection, it should be possible to use the gross alpha-method to estimate past atmospheric concentrations of210Pb. Measurements on filters after elapsed times of up to 15 years show that such determinations are feasible. Akadémiai Kiadó, 1992 Sheets R.
