Description

Radon (222Rn) is a prominent background source in the low-background SNOLAB experiments. Silver doped zinc sulfide (ZnS:Ag) is used as a scintillator in a radon counter known as a Lucas Cell. Commercial ZnS:Ag is readily available, but it lacks the purity required for low-background applications. This project focuses on synthesizing ZnS using selective precipitation to remove trace impurities, then doping it with silver and testing it against the commercially made product.
