摘要：

Our previous studies indicated the suitability of tobacco plants for biomonitoring remediated depositories, due to their Po-210 and Pb-210 accumulation ability. The methods and requirements of testing Pb-210 uptake by leaf-surface adsorption was investigated and implemented in the construction of a controlled environment. Uranium ore (theoretical Rn concentration 638 Bqm(-3)) was the main source of radon and progeny. Rn concentrations were measured by RAD7, AlphaGUARD, EQF 3220, RTM 2100 and CR-39 SSNTDs (411-516 Bqm(-3)). Activity concentrations of the attached and unattached fractions were determined by EQF 3220. The results are indicative of good measurement setup for tracking Po-210(Pb) uptake pathways.
