  New measurement and assessment techniques have been applied to the
radiochemical re-evaluation of the Trinity Event. Thirteen trinitite samples
were dissolved and analyzed using a combination of traditional decay counting
methods and the mass spectrometry techniques. The resulting data were assessed
using advanced simulation tools to afford a final yield determination of $24.8
\pm 2$ kilotons TNT equivalent, substantially higher than the previous DOE
released value of 21 kilotons. This article is intended to complement the work
of Susan Hanson and Warren Oldham, seen elsewhere in this issue.
