Also 42-Ar is a source of ß-radiaiton, that is used in tubes, even starters for fluorescent lamps!
Anyhow, radioactive isotopes are more frequently used in electron tubes. Particular tubes for transmitting and radar purpose. Thorium is allied to Tungsten in filaments for HF power tubes to enhance emission and CO-60 is used to enhance ignition of TR-cells (Transmit-receive cells), who are used to short-circuit the receiving part of an radar system during a transmitting a pulse. Thus to protect the delicate electronics in the receiver front-end. eric Van: [email protected] [mailto:[email protected]] Namens Paolo Cravero Verzonden: zondag 12 maart 2017 21:44 Aan: [email protected] Onderwerp: Re: [neonixie-l] Radioactive Nixies - Study Very interesting Jonathan. Any chance you could share a picture of the little warning sign and its position? I have very few of those Nixies and all tested negative, but my counter is quite insensitive. Thank you!
