Brachytherapy-Model 44G Well Chamber
Company : Best Medical International Inc
UMDC Code : 382402
The 44G is a hermetically-sealed re-entrant well ion chamber, requiring no air density corrections. The fill gas is pure argon at an absolute pressure of 23.5 psi, which provides three distinct benefits. First, through photoelectric absorption, argon enhances the response at low energies emitted from 125I and 103Pd. Second, because of its low electron attachment coefficient, argon provides a higher ion collection efficiency, making it more suitable for 10 Ci HDR 192Ir sources. Third, the positive pressure provides long term constancy measurements with the ability to verify the chamber seal.
