Determination of lead-210 in environmental samples.

摘要

Three indirect radiochemical methods for determination of lead 210 in environmental samples have been compared. These are Cerenkov counting gross alpha and beta counting and alpha spectrometry. Lower limit of detection counting efficiency, chemical recovery and analysis time. For the three methods have been compared. The results, based on radiochemical analysis of reference and natural samples, have been shown that the studied methods can be used for determination of lead 210 in environmental samples with low levels.
