Many studies on resuspension are based on experimental data from the Chernobyl region. Garger et al. (1997), using the data from Pripyat and Baryshevka, found
an empirical formula for the resuspension factor, which decreases following a
power law in function of time:
K t
ð Þ $ t
À1:4
Also based on Chernobyl region time series of data, (Hatano and Hatano 1997)
propose a similar power law dependence:
K t
ð Þ $ t
À1:33
Decades after Chernobyl, the resuspension of radionuclides continues to be
studied (Viswanathan et al. 2000; Maxwell and Anspaugh 2011; Garger et al.
2012) in order to achieve a better agreement with extended experimental data series
and to better understand the resuspension process in the long term.
Garger et al. proposed in 2012 a modified exponential formula based on a longer
data time series than his first research from 1990s.
