Re: S-35 Radioactive Contamination

[LENTZC <LENTZC@aa.wl.com>]

Ninni,
About two years ago we had a similar incident with 35-S at our facility. The
researcher spilled approx. 5 nCi on his arm. We consulted Radiation Safety
Associates in Hebron, CT. to perform dose calculations.

I would be happy to share these with you or anyone else on radsafe.
Unfortunately my radsafe mail does not indicate the e-mail address of the
sender, so if you want a personal reply, please include your address in the
message. Or better yet, send me your fax number and I will shoot you a hard
copy.
