Picture?

It would be nice to get a picture of the lake. Does anyone know of one in the Public Domain? The Jade Knight 23:46, 26 December 2005 (UTC)[reply]

It should be possible to get one through Google Earth, but I don't know the coordinates. Simen 88 19:11, 24 June 2006 (UTC)[reply]

I'm relatively sure the lake can be seen here, but I can't confirm it. If it is not in fact the very dry patch shown on that satellite image, it will still be nearby. The Mayak plant is directly to the west. Livedo 21:50, 1 April 2007 (UTC)[reply]

The exact coordinates (atleast according to google earth) are: 55°39'42.03"N and 60°51'16.01"E. BebopBob 21:00, 31 October 2007 (UTC)[reply]

The actual Coordinates are 55°40'40"N 60°47'52"E it is just south of the complex.--DieselDude (talk) 21:33, 15 May 2009 (UTC)[reply]

there is a picture of the lake on wikimapia that would be great to add(karachay is NOT the large filled lake to the southeast of mayak. it is a tiny lake just south of mayak and northwest of large filled lake if you go to the googlemaps view of mayak and select the wikipedia option the w should be right on it. .) go to wikimapia.com you cant miss it. i hope that helps.68.206.123.207 (talk) 21:34, 19 June 2009 (UTC)[reply]

This article (in a major Norwegian newspaper) claims that it's top picture comes from Wikimedia; however a reverse google search doesn't show it? Huh. http://www.dagbladet.no/2015/08/30/nyheter/utenriks/forurensning/miljo/russland/40870876/ Kyrsjo (talk) 21:55, 30 August 2015 (UTC)[reply]

Lethal dose

500 roentgens in 5 hours = 100 roentgen per hour doesn't it? (User:66.186.69.169)

No, it's not. It's something like this:

1200 roentgens per day
500 roentgens per five hours
200 roentgens per hour

bogdan 00:14, 27 December 2005 (UTC)[reply]

I've let my edit of 100 röntgen per hour stand because I can't find a source for the strange progression you offered above. Can you cite a source? I looked at a bunch of other methods for measuring radiation dossage in humans, but they were all too complicated for me to make a call, so, again, I left it alone. See: Sievert, Gray (unit), ionizing radiation, and radiation poisoning. Anyone who knows what's what is welcome to fix the article. —ZorkFox 02:29, 27 December 2005 (UTC)[reply]

Well, it's a little more complicated than that. Radiation is ultimately measured in nuclear disintegrations per second. However, not all disintegrations are equal. The higher the frequency of the produced radition, the more dangerous it is (because more energetic photons can more easily break the molecular bonds found in the cells in your body). So 100 roentgens from something that produces low-freuqency radition is nowhere near as toxic as something that produces 100 roentgens of high frequency radition. That's why the Equivalent dose scale was invented, in order to take this into account. Raul654 02:39, 27 December 2005 (UTC)[reply]

So, what we really need it someone who understands exactly what kind of radiation the lake is putting out, who can also evaluate all the integrals and whatnot to determine the actual danger level of the lake. In the meanwhile, I propose to make the statement more general; something like: "The level of radiation dossage a human would receive at the lake in one hour is significantly higher than a lethal dose." How does that sound? —ZorkFox 02:47, 27 December 2005 (UTC)[reply]

I'd prefer to keep specific, cited numbers in the article. Raul654 02:50, 27 December 2005 (UTC)[reply]

I've adjusted the article accordingly. Raul654 02:52, 27 December 2005 (UTC)[reply]

I also added some external links in English... which might actually have enough information to expand this article and/or start one about the Chelyabinsk-40 site (or Chelyabinsk-65, as it is apparently now called). —ZorkFox 09:51, 27 December 2005 (UTC)[reply]

Let me explain. In Soviet times, closed cities were called by the name of the nearest big city (in this case, it was Chelyabinsk (the city I live in, BTW :))) plus the last digits of the postal code. After the collapse of the Soviet Union, many if not all of the "closed cities" were given their own names, e.g. Zlatoust-36 became Trehgorny. So, in this case, the first name for this very town or city (population ~100,000) we are talking about was Chelyabinsk-40, then it was changed to Chelyabinsk-65, and since 1990s, it is Ozersk or Ozyorsk (Озёрск). But actually, the nuclear wastes storage & reprocessing plant is located outside of this town, about 8 km to south-east. --Anthony Ivanoff 19:13, 6 January 2006 (UTC)[reply]

Can someone point me at the correct "weblinking" guidelines mentioned by Ghirlandajo on the history page for this article? I looked around a little and found some stuff that seems appropriate, but it doesn't weigh in on what language external links should use. Personally, I can't read a single word of Russian, and though I realize the English language Wikipedia isn't here solely for my use, I can't be the only one. :) —ZorkFox 10:55, 27 December 2005 (UTC)[reply]

As best I know, foreign-language links are recommended, when there are no websites that contain the same information in English. See Wikipedia:Manual of Style (links) --Ghirla | talk 11:03, 27 December 2005 (UTC)[reply]

Unfortunately, I can't tell whether or not the sites have similar or different information. :) The style guide says that English links are preferred, so I would still consider the Russian links for removal, but I'll let a consensus decide. —ZorkFox 02:37, 28 December 2005 (UTC)[reply]

Feel free to ask me to translate anything from Russian. --Anthony Ivanoff 19:13, 6 January 2006 (UTC)[reply]

Coordinates

The coordinates Google Maps gives are a bit off. There is a filled lake there alright, but it appears to be much larger than the 750m by 450 m[1] Lake Karachai.

These maps indicate a lake of the correct size, to the northwest, closer to the combine: [2] [3] [4] [5]

Furthermore, Lake Karachai was referred to as Reservoir B-9 (Водоем Карачай В-9) [6], which this map [7] also indicate as the smaller lake (the larger one doesn't have a number and may never even have been used as a reservoir - this map [8] lists it as "ash dump number 2" (Золоотвал No2).

I have adjusted the coordinates to 55°40'38"N 60°47'54"E.

Footnote: The maps were taken from here: [9][10][11][12]

concrete lake???

it says in the article that the lake is now completely covered by concrete, but does not give any refferences. the sattelite and aerial views of the lake also contradict this statement. i personally think this statement is just an assumption based on the pain of salvation album, and the concrete blocks inside the lake.68.206.123.207 (talk) 16:47, 20 June 2009 (UTC)[reply]

Yeah, I think you're right. The only website that said it was covered in concrete (with a quick Google search) was this one, which I don't think is very reliable as it seems to be just an out-of-date copy of Wikipedia. N Segick (talk) 04:18, 8 September 2009 (UTC)[reply]

sparing no expense

"sparing no expense. Little to no consideration was paid to worker safety or responsible disposal of waste materials." If there was poor worker safety and improper disposal of waste materials then it's definitely not sparing no expense. The sub-clause is entirely unnecessary and overtly false.
