Identification of ${}^{210}$Pb and ${}^{210}$Po in the bulk of copper samples with a low-background alpha particle counter

XMASS collaboration, K. Abe, K. Hiraide +39

We established a method to assay ${}^{210}$Pb and ${}^{210}$Po contaminations in the bulk of copper samples using a low-background alpha particle counter. The achieved sensitivity for…
