[ RadSafe ] Ra-226 Static eliminator bar

[Yusko, James (DEP)]

Good afternoon, all,

Brian, you asked about common uses.  We have seen these attached to teletype units, even old printers, to eliminate the static electricity from the sheets of paper output from those machines.  It was later discovered that tinsel, similar to old Christmas garlands, was equally as effective.

Those radium static eliminators we had seen from teletypes, etc., were about 30 cm (12") long, however.

Brian,

The following link shows a 1949 title about the subject, "Safety factors for radium-containing static eliminators used in printing and allied industries."  It sounds like it could be an interesting read, if you have access to the journal.

http://www.ncbi.nlm.nih.gov/sites/entrez (you might have to do a search on the title above).

Also, you might contact some of the larger state radiation control programs.  They might have come across some of the devices.  It looks like NY is a good candidate (one of the manufacturers was located there) and a PA blurb indicated that they have recovered several devices.


Nicolas, thank you for sharing the interesting article on the subject.

Does anyone have any information on the use of Ra-226 for static eliminators?  I have a colleague that found one that's approx 30" long, maybe ~100 uCi.  There's no printed (engraved, etc.) information on it.

Any information would be appreciated.  Yes, I know Po-210 is common now, but this is clearly Ra-226.

Thanks,
Brian Rees
