I wonder if these could be resurrected by attaching a radiation source to the envelope. I'd guess that the envelope would probably block alphas, so no point in taping an Am241 source from a smoke detector to the envelope, but possibly a small, exempt size beta source of Sr90 might get one back in action? Greater health risk from the B+ on the tube than from such a tiny radiation source. -- Matthew Smith Business: http://www.smiffytech.com Blog: http://www.smiffysplace.com Linkedin: http://www.linkedin.com/in/smiffy Flickr: http://www.flickr.com/photos/msmiffy Twitter: http://twitter.com/smiffy ABN 16 391 203 815 -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
