i have found these photos here. vachagan made them back in the winter 2014.

that was the next day after a car crash accident. in front of me there were two girls and one guy from azerbaidjan. vachagan was asking them about differences and similarities between azerbaidjani and turkish language. they said that formerly they were watching movies on tv or in cinema in russian, they were receiving films from russia. now they receive films from turkey, with turkish translations. she said, when the film comes to the end i realize that i didn’t even notice that it was in turkish, not in azerbaidjani.

we also asked them about the orthography. she answered that they’ve changed orthography 5 times - they were writing with arabic letters, then, during short independence in 1918-20 in latin letters, then cyrillic letters, then now again latin. she said “our president gave a promise that in two years all books will be reprinted with the new orthography”. “and, did they manage to reprint them?” - i have asked. “no” - she answered.

also she said very interesting and typical thing for someone from a country with authoritarian regime: she said she does not see any other good candidate rather than their ilham aliyev. she said “if not him - then who?”. well, isn’t it obvious that he did everything for you to think like that, my dear?

then they started to ask us about the language. they’ve said “we know there are eastern and western armenian languages. do you understand each other? how do you live in one small country and speak two languages?”

i have answered, that well, languages do not differ that much, and we perfectly understand each other, except for a couple of words that may have a bit different meaning. and i have added, that western armenian is spoken in the west only - in europe, usa, latin america. not in armenia as a rule.

and she asked naively - “why?” i hate mentioning the “genocide” word and the theme, so i remained silent for some time.

then the azerbaidjani guy who sat next to her, a guy in a shirt with some horizontal fur line on it, he smiled happily and started to whisper something in her ear. his face exprecced great satisfaction.

she said “ah, i understand”.

My friends helped me to measure radioactivity of my lenses. I had some yellowish lenses, and had an assumptions that some of them are possibly radioactive. However, I did not know until this time if it’s true.

These are the results of our measurments. We have been written down only the maximum values.

I am not able to disclose information about the person who conducted the measurments, the place, and even the device name.

background front el. ( μSv/h) rear el. ( μSv/h)
Asahi Pentax Super-Takumar 35/3.5 0.08 0.08
Asahi S-M-C Super-Takumar 135/3.5 0.086 0.08

Mamiya AUTO Mamiya/Sekor (DTL series) (identified thorium-232) 50/1.8 0.24 1.164
Mamiya AUTO Mamiya/Sekor 55/1.4 0.09 0.09

Apparently, Mamiya/Sekor 55mm which is reported to be radioactive[1] is not active according to our measurments. May be there been different 55mm f1.4 lenses in production?

The only really dangerous lenses we found in my collection were Mamiya/Sekor 50mm f1.8 which came with my Mamiya 1000 DTL. It’s also yellow. The device could identify the radioactive element, which is, no wonder notorious Thorium-232.

When measuring Helios 85mm, the radiation level went lower than the background, when the device got closer to the glass: that’s because it’s built from solid metal, and it filters background radiation at it’s front part which has small hood. These lenses are also a bit yellow.

What was surprising, that lenses from the FED-3 camera, officially promoted as lenses with lanthanum optics, seem to have no dangerous level of radiation.

We have also measured the Mamiya-1000 DTL viewfinder, and FED-3 viewfinder, they are clean and safe to use.

Another test we conducted - we were trying to get the device notice the radiation when the thoriated lenses were on the camera. We could not detect radiation by moving the device sensor arond the lenses, near m42 mount, everywhere around the camera. It seems that the metal parts filter radiation well, and even those lenses are safe to use.

I may update this information here
