Na starim, novi satovi Super Luminova BGW9.Nisam pročitao nigdje na novim za Tricijum i sl.Ne tvrdim.



Skinuo sam sa stranice Omege dio teksta iz teh.opisa satova. my favor
Today, the Planet Ocean also has the advantage of an automatic Co‑Axial Master Chronometer movement, offering the very best in precision and magnetic resistance. Furthermore, the design incorporates classic watchmaking details such as the helium escape valve, GMT functionality, and dials with Arabic numerals and Super‑LumiNova. Not just for divers, these iconic Swiss watches can be worn by anyone who adores style.

Recce ::Idi u TRZ tamo ce verovatno moci da pronadju nesto za merenje

Da nemas ti koju kod sebe?

Samo nemoj da mu daju stare skale sa T-55... Isto svetle, samo sto je u pitanju radijum, a on je zapravo opasan.

Inace da resimo misteriju, moji stari podaci, izmericu ponovo sa fotkama kada mi burazer vrati pribore*.
Privezak sa tricijumskom cevcicom 15x3mm:
- sa zatvorenim alfa/beta filterom na Radiascan 701A - 0.21-0.25uSv/h (pozadinska 0.07-0.09uSv/h - posle babe kazu "veliko zracenje u Batajnici" ). Radiacode 101 kaze da je zracenje samog predmeta, sa kompenzacijom prirodnog fona 0.17-0.19uSv/h i da skoro svo potice od zakocnog zracenja.
- sa otvorenim beta i alfa filterom na Radiascan 701A dobijaju se vrednosti 0.27-0.31uSv/h, veoma malo povecanje u odnosu na cistu gamu, jos jedna potvrda da je prakticno sve sto se detektuje kao gama zakocno zracenje od udara beta cestica u staklo i plastiku, i beta prakticno ne prolazi staklo i plastiku..

Sve ovo je na kontaktnim distancama, vec na 5cm se jedva vidi povecanje u odnosu na fon, a na 10cm nema nicega.

*Trenutno se voze avionom, da vidimo koliko se nakupi za 4 leta od po sat i po-dva.

Eto mernog dragovoljca,a ja se bas nadao da ce Recce sta iskopati.

Trenutno nisam kuci tako od mene neke koristi i nema.
Inace, tricijum se i dalje koristi u satovima (ja imam Luminox sa 16 svetlecih oznaka a koristi ga i Rolex). Radijacijska opasnost od takvog izvora ne postoji. Jednostavno, tricijum je u prirodi prisutan i u lisnatom povrcu, mleku i mesu. Kumulativno, na taj nacin ga unosimo daleko vise nego sto bi nas (uslovno) ozracio kroz optiku.

Slobodno proveri i ti, da ne bude da lazem narod i trujem ga.

Rolex koristi Chromalight što je kao i Super-Luminova na bazi stroncijum aluminata.

Citat:Mit ihrer neuartigen Leuchtmasse sorgt die Chromalight-Anzeige des Zifferblatts für eine verbesserte Ablesbarkeit im Dunkeln, was für Taucher von wesentlicher Bedeutung ist. Dreieckig, rund, rechteckig: Die Indizes sind mit ihrer schlichten Form und sinnvollen Anordnung schnell und eindeutig abzulesen – ebenso wie die breiten Stunden- und Minutenzeiger, wodurch jegliche Verwechslungsgefahr unter Wasser vermieden wird.

Radiacode 101 je scintilatorski detektor, brzi i precizniji od klasicne gajger-milerove cevi,dakle ne bi trebalo da bude nikakve greske tu.

To replace radium, Rolex switched to tritium as the go-to luminescent material for its dials. Like radium, tritium is also self-luminous, however, it is a low-grade radioactive material, therefore not nearly as dangerous. Rolex used tritium ...

A luminescent material is needed on the hand and hour markers in order for a timepiece to be able to be read in the dark. For the most part, the emission of light on a watch is caused by either photo luminescent material, which is determined by an exciting luminous radiation, or a radio luminescent type, something determined by the radioactivity of the material.

Rolex used the radioactive material Tritium, which refers to the chemical used on the hands and hour markers of the watches, which causes them to illuminate. To indicate the amount of the radioactive material, Rolex began marking a designation at the bottom of the dial:


T SWISS MADE T: the radioactive material Tritium is present on the wristwatch. The amount of radioactive material emitted is limited to a maximum of 25 milliCurie.
SWISS T < 25: indicates more specifically that the wristwatch emits an amount of Tritium that is less than the 25 milliCurie limit. This indication can be found on all Submariners from 1989 to 1997.
SWISS T 25: the wristwatch emits the maximum allowable amount of Tritium (i.e. a full 25 milliCurie).
SWISS (or) SWISS MADE: wristwatches produced after (around) 1998, indicates the presence of LumiNova as the luminous material. These terms were also the indication on wristwatches produced prior to the 1950s, when Radium was used as the luminous material. However, at that time "SWISS" or "SWISS MADE" simply indicated that the watch was made in Switzerland.
T: deposits activated by tritium
Pm: deposits activated by promethium
T 25: indicated deposits activated by tritium on higher value watches
Pm 0,5: deposits activated by promethium indicated on higher value watches.

Timepieces that feature radio luminescent emissions are, for the most part, designed for very specific uses: aviation watches such at the GMT-Master I & II or professional diver watches such as the Submariner. When a radioactive material is used, the ISO 3157 Standard has strictly defined guidelines that allows only low values of two types of radionucleides to be used: tritium (3H) and promethium (147 Pm), materials that emit a radiation of low energy.

It is important to mention that Tritium used for Rolex watches with luminescent parts are not harmful when sealed inside the watch. Around 1998, watchmakers such as Rolex changed the designation to read SWISS or SWISS MADE, when they replaced the Tritium with LumiNova, an organic, non-radioactive chemical, as the source of luminescence.
