Linda,

The use of radiation as a curative treatment will usually result, as I
understand it, in a quick drop that tends to level out over time while
cancer cells are self-destructing.  Although 0.06 is almost to the bottom of
the readable scale, it might even go lower.

The fact that Jim's went to the cellar, I cannot help but to believe that
all his cancer, or almost all his cancer, was contained in a small area on
his prostate bed.

Let's face it; you're going to be terribly disappointed if his PSA starts to
rise (three times).  But, the fact is, you have really good reason to hope
that he was cured with his one-two punch.
