Re: scale source

["Joe Alvarez" <jalvarez@auxier.com>]

I had a surface tension device in about 1968 that had 2 Po-210 sources,
shortly after receiving it, the manufacturer reported problems with the
sources and replaced them with Ra-226.  Since your source is still active
after 20 years, Ra-226 is a good guess.
