Yes / No.   Very aware of that potential.  There are a number of
science issues relevant to the effects of radiation induced damage
which promote inhomogenity.   IF.....   if  Dapoz is able to
demonstrate focal defects characteristic of alpha particle damage, this
does not exclude chemical induced color change, but strongly weights
toward the former.  If a magnified view fails to demonstrate any focal
defects, chemical color change remains STRONGLY in contention.  Results
are only a logic 'sort', not proof of one or the other.

Its not even a logic sort - absence of evidence is not evidence of absence, despite Bush & Blair being hung by that petard!
