Development of a method for measuring rare earth elements in the environment for future experiments with gadolinium loaded detectors

Abstract

Demand to use gadolinium (Gd) in detectors is increasing in the field of elementary particle physics, especially neutrino measurements and dark matter searches. Large amounts of Gd are used in these experiments. Therefore, to access the impacts of Gd onto the environments, it is becoming important to measure the baseline concentrations of Gd in the environments. The measurement of the baseline concentrations, however, is not easy due to interferences by other elements. In this paper, a method for measuring the concentrations of rare earth elements including Gd is proposed. In the method, an inductively coupled plasma-mass spectrometry is utilized after collecting the dissolved elements in chelating resin. Results of the ability to detect anomalous concentrations of rare earth elements in river water samples in the Kamioka and Toyama areas are also reported.
