Tritium Survey Instruments

Abstract

Portable counters for the detection of surface and air tritium contamination are described. The surface monitor uses a sponge rubber seal to the surface with an argon-methane counting mixture being admitted during measurements. The air monitor mixes methane with the air before counting, and is capable of detecting a tritium concentration of 10−5 mc/cc of air.

“…52), the other a ZnS(Ag) scintillator with film recording from NYU (Ref. 53). One gave responses which varied by factors of as much as 10 when repeat runs were taken; the response of the other varied by a factor of as much as 3, but the dosimeter only increased its response by a factor of about 3 when radon concentrations increased by a factor of 10.…”
