ID this Russian gun sight please ~!

[komesho]

This is a Russian gun sight "picked up" during the South West Africa / Angolan border war of the 80's.
Can anyone ID it or supply me any info on it ~?

Please excuse my English ...

Periscopic artillery compass ПАБ-2М (PAB-2М) (bussol)

Periscopic artillery compass ПАБ-2М is the main instrument for targeting and data preparation for firing.

You can use it to solve all the tasks performed with the help of binoculars, a periscope, or stereoscopic, and in addition, to determine the magnetic azimuth to the target.

Bussol ПАБ-2М is an eightfold increase, the field of view of 5 °, periscope-elevation (using the supplied periscope) 350 mm, mass in the position of 2,5 kg.



Be careful! Warning!

Can have the scale to the phosphor continuous action, which emit up to 3 milliR / hour (at a rate of 15-30 micro R, h) ie 100 - 200 times higher than natural background.

Thanks for the quick reply.
What do you mean with.......

What is being emitted ?
What is the natural background ?

According to some resources this device can emit ionizing radiation and you can receive up to 3mR/hour of radiation dose, while normal background radiation is about 15-30microR/h, so it's about 100-200 more then normal.

in other words you are probably going to have cancer

This artillery sight propably contais a little bit of tritium that is a lightly radioactive material.

Tritium is used in small amounts in gun sights and clock faces because it glows in dark so you can see the numbers and markings more easily.

It shouldn't be radioactive enough to cause health risks unless you sleep with it every night for years or something.

[komesho]

So does it contain dangerous phosphor or not so dangerous tritium ~?

[kcher]

And phosphorus and tritium dangerous in certain concentrations and long exposure time.
Maybe your device does not contain these substances and may contain. Just be careful. Do not carry it with him constantly and do not disassemble. It is better to inspect the unit to the radiation in the nearest laboratory or medical office.

As an example

Quote:
Radioactive aviation watches found recently Specialists
NPO "Radon" in one of the garages village Mosrentgen Lenin
Area suburbs. The source of radiation has been the usual
air time unit, the radiation level at the surface which
amounted to 1400 mR / h (recall that the norm - 20 mR / h). As
it turned out, the clock was covered with so-called svetosostavom
permanent actions (SAP) on the basis of radium salts. In 40-60's
this substance covered not only in times of war
Technology instrument panels, optical sights, but also toys,
as well as Christmas decorations. The harmful effects of radiation on the same
human body had not yet been studied. (p.1)

The radioactive isotopes of phoshor have a half-life of 25 days at best.
They decay too quickly to be useful in any instrument that is meant for long time use. The substance would be reduced to insignificant amounts in just a year or two.
The only phosphor isotope that doesn't have a short half life isn't radioactive at all since it's stable. They wouldn't have put a radiation warning on the instrument had they used that one.

Why does the translation talk about phosphor then? I don't know. Maybe it's supposed to mean luminescence.

[kcher]

Exactly ...
Problems with translation ... :oops: means any radioactive luminous substance, not just phosphorus ....
