Analysis of Beta-Decay Rates for Ag-108, Ba-133, Eu-152, Eu-154, Kr-85, Ra-226, and Sr-90, Measured at the Physikalisch-Technische Bundesanstalt from 1990 to 1996.
For determining activity degree of elements such as U-238, Ra-226, Th-232, Cs-137, and K-40, we sent 4 soil samples to Iran's atomic energy agency laboratory (Jaber-ebn-Hayyan laboratory), and measured by HPGe Gamma spectrometer with germanium detector.
These samples were transferred from the bags into clean air-tight containers and sealed for 28 days in order for the samples to attain secular equilibrium and also to prevent escape of Ra-226 gas.
