Esr dating in quaternary geology
The trapped electrons form para-magnetic centers and give rise to certain signals that can be detected under an ESR spectrometry.
The amount of trapped electrons corresponds to the magnitude of the ESR signal.
The dose rate is found from the summation of the concentrations of radioactive materials in the sample (internal dose rate) and its surrounding environment (external dose rate).
The dosages of internal and external radioactivity must be calculated separately because of the varying differences between the two.
Abstract Because of lack of Quaternary volcano activity in China, Quaternary sediments become the main dating material in the study of geological structure, topographic feature and environment evolution,etc.
