It is possible to count the following radionuclides: Pb-210, Cs-137, Am-241, Cd-109, Co- 57 as well as Ra-226 (which is the average of Pb-214 and Bi-214) in sediments using the HPGe method (High-Purity Germanium detector). These steps (drying of the sample, crushing and homogenization) can be done by the customer, or by our people at the laboratory, which will make for a slightly higher price per sample.
