Thanks, Charlie. Most of the folks I know are too old to move in those

Jim,
You might be able to shorten the treatment time if you happen to know
someone working at a tanning salon.

My slightly radioactive Pentax Super-Multi-Coated Takumar 50/1.4 is
undergoing a sunshine treatment in hopes of reducing the slight
discoloration of the 3 rear elements. The recommended exposure is about a
week, but may get extended because of bad weather days. You may note that
this photo was taken with with a Takumar 55/1.8, which also has
Thoriumdioxide glass, but is not discolored enough to notice.
