Tritium og bruge på ure - fra min blog

[longbear]

Godt skrevet John - godt emne

Jeg har selv gravet lidt i emnet med en Bundeswehr-vinkel, og deraf fandt jeg spændende/geeky dokumenter bla vedr. tritiums militære brug som accelerator i atom-bomber. Tritium var/er derfor omfattet af atomare ikke-spredningsraftaler!

Som du nok ved er der et vedholdende rygte om at Heuer Bund fik skiftet skiver pga forbud mod generel brug af Tritium i BW. Sagen er bare den at ur-skiver/visere ikke ser ud til at være omfattet af dette forbud. Jeg researcher stadig

Nedenfor et indlæg jeg skrev andetsteds. Det er mest mili-bu**-shi**, men de postede links vil måske være af interesse. /longbear

Hallo Felix,

this is a very interesting topic, that has been discussed on several sites over the years. Not only is it interesting for the Heuers but also for the other Bund watches and for other german military items like night sights etc.

I have several times read that Tirtium was totally banned in the german army after a certain date, and started wondering why still so many watches still had tritium dials. Even the late Bund watches Orfina etc., seems to carry tritium even though they were released after the Heuer -9456 was "introduced".

I started researching the use of Radium and Tritium in Bundeswehr, and found some interesting documents. It seems like Tritium was not banned on watches (and other items) if they were marked 3H. Radium was banned as of 1966-12-31, but due to various isssues the use of Radium was extended, and especially equipment with "dials and hands" was excluded up until the early 80'ies

Some info found in the report from "Radarkommission"

interesting is the quote from VMBL (VMBL 1980 page 404 #9) which is mentioned on middle of page 33 (section 3.1):

"Alle Gegenstände, auf die andere als mit Tritium (H-3) oder berührungssicher abgedecktem Prometium (Pm-147) radioaktiv angeregte Leuchtfarben aufgebracht sind, müssen ausgesondert und als radioaktiver abfall seseitigt warden."

also bottom 32 and top 33 is interesting including footnotes.

PS. pure tritium is used as an accelerator in nuclear bombs, and it seems to be covered by several international agreements about non-proliferation. I found some quite "heavy" reading on civil and military use of tritium - quite interesting, but not watch related. the total civilian demand for tritium was only 800g per year in the late 70'ies at $10.000 per gram. the prise rose later to $29.000. The paint for one watch is estimated to contain 0,1 to 2,5 ug of trit
