Comment:
Water: weight loss by drying
Pb210: conc. HNO3/HCl digestion, Po210 deposition , Po210 alpha counting, surf. barrier detector (Erlenkeuser and Pederstad, 1984)
Pb(Po)210 age: CIC model. CIC Model Parameters: 191.67 [Bq/kg] Initial Conc.; 9.94 [Bq/kg] Supported Conc.; 0.21 [Bq/kg] Std e of Supported Conc.; 1980 Start Year [a AD]; Halflife: 22.3 a; (Erlenkeuser, 1985)
CS137: dry sed., gamma counting, low level HPGe-detector (Huebener et al, 2009)
