Very nice instrument. It even uses the well known SR connectors, that were used all over the bloc. You can still find these aircraft connectors being used in welders (to connect remote control) or even electric locomotives to connect various installations.

I have quite a few photomultiplier scintillation radiometers at home - I saved them from electrical waste. They were used in the company for the production of glass bottles - they were used to measure the level of molten glass in the channels. On one side of the channel was a radioactive emitter and on the other side a scintillation detector - and the lower the level of the glass, the more radiation passed through the channel. When I feel like it, I want to try them to see if they all work. But I also have a few radiometers, e.g. RBGT-62 or IT-65

Is planting apple orchards, or any other concentrating mechanism, as a means of cleaning radioactive minerals and elements from the soil a viable long term cleanup strategy? Or is it best to just let the radioactive elements and minerals decay where they are?
@ChernobylFamily

Not really, because contamination e.g. in the case of the Zone is a composition, and there is a migration to leaves. There was an issue with red forest (for instance), when the trees has been bulldozed, and new were planted; after the first fall of leaves a surface contamination increased, as they got much through the vessel system of the trees. The past practice shows that the best application for trees/grass is preventing the wind erosion (that's why ditches for radwaste are always covered with grass) which is a serious factor especially at the early years after contamination occurred. Additionally, the sorbing rate (let's call it this way) is not very effective, when it is possible to clean the surface layer, better to use mechanical intrusion, chemical sorbing/adhesion compounds, etc.

Interesting, thank You for clarifying things here. There are not really any person i can ask easily here who can give the correct answer, so most of what i found i had to use the papers from the government instances and they are usually not really going into details about the exact methods of analysis, or why certain species are supposed to this or that, they usually just say things like collect this or that and send it in for analysis and we will show you a national diagram and give You instruction of what food needs to be discarded if needed, not exactly very informative to my research to be honest.

Honestly if the tubes are still intact i think the old instrument are probably as exact as any modern one made for field work analysis, interesting. I fully understand that You don't want to risk destroying it, but i can guess the function of the units and it was interesting to see the actual tubes in the spare part box.

That was not really about destroying, just to assemble it back is a headache (we still have a few of these running in the zone, guys adviced). Well, precision of this is sig sificantly lower comparing to modern, however this is nothing comparing to the need of calibration nearly each time before use. That is pretty inconvenient.

@@ChernobylFamily I can guess that, i remember the work only for calibrating the oxygen and Ph meter, hygrometers, etc when i was a student and those are probably not even in for the race here... Ha ha Personally i find those old things highly interesting. I remember seeing pictures from the clean room on the old nuclear power-plants here had similar, but even more advance triple tube equipment, but those are probably only useful in the laboratory, i am not an expert, but i imagine there would probably be too much disturbing factors for use on field samples, probably that's why they did use this type of high sensitive meters that could be brought to the spot instead, but probably pick up a lot less interference my guess. It's honestly the first time i seen the inside of the box. Abut the mushrooms, when i found them, i actually did notice that they hawe a lot more dense body and a very hard shell compared to more common species which usually has that traditional soft, watery body. I guess the government instances does only present statistic for things classified as human or domestic animal food in the chain of human food production, that's why so much indicators are left out. I happened to stumble upon those papers from a side study made by the national museum archive of nature and wildlife, it where originally about those fungus as general indicator species. But i did not found the in depth details so i think i will send them an email and ask more about it because those fungus always deeply fascinated me since i was a child, i did not knew that they did work as the apple seeds for accumulating radiation.
