Comment:
The supported 210Pb activity, defined by the 226Ra activity, was determined on each interval by subtracting the 226Ra activity, defined as the average of the measured 214Pb and 214Bi from total 210Pb. In many intervals no correction was made because the measured 226Ra was less than the method detection limit of 0.3 dpm/g.
