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.
Need feedback re issue of uniform glass based versus surface....

But...... my
limited experience in examination of radiation altered glassware
suggests inhomogeneities are always present when the damage is from
ionizing radiation (i.e. not chemical induced color change). Dapoz,
can you acquire a magnified view of the central region of this lens
image to look for 'bubbles' or other tiny focal defects characteristic
of radiation damage???
Carry on...
