Abstract
A method of assembling a scintillation detector including placing a scintillator crystal in a casing, and forming a sealed casing having a controlled atmosphere different than ambient atmosphere, wherein the controlled atmosphere includes an inert gas and a trace gas in an amount of at least about 1 vol % and not greater than about 30 vol %, wherein the trace gas is selected from the group of materials consisting of hydrogen, helium, neon, krypton, xenon, and carbon monoxide. The assembling method further includes testing the sealed casing for leaks by detecting the presence of the trace gas.
