Abstract
The 19F(n, 2n)18F reaction has been adapted to the analysis of fluorochemical-treated fabrics, using Teflon film as the reference standard. The ultimate success of the technique depends on effective retention of active 18F nuclei which can escape from both the fabric and the Teflon standards; this is accomplished by sealing all samples individually in thin Mylar film before activation. Recoil protons produced in the fabric substrate create a measurable amount of 18F in the basic unfinished fabric through the 18O(p n)18F reaction this compensates for systematic deficiencies encountered in measurement of the total 18F-activity of the finished fabric.
