Re: Technetium eluents

[rotman family <rotman@mip.net>]

The NRC no longer has an Al test requirement in the regulations, however, it
may show up in various forms via license conditions.  In any case, it is
extremely rare for Al to breakthrough with modern generators.  I have eluted
generators for 20 years, and have yet to see a single breakthrough.
