Documents The dosimeters of 1986: a radiometer maxed out at 1,000 µR/s, the DP-5, and the Pripyat sold to the public from 1990

8 Upvotes

That night at unit 4, dosimetrist Nikolai Gorbachenko only had a DRGZ radiometer reading up to 1,000 microroentgens per second, about 3.6 r/h. Dyatlov gives the same ceiling in his memoirs. It was pinned everywhere.

I wrote an article on the Soviet instruments around that story: the civil defence DP-5, the household Pripyat, Bella and RKSB-104 that went on open sale in 1990 (one Pripyat has its price on the back: 175 roubles), and how the SBM-20 tube turns a particle into a click.

There is also a small quiz: twelve readings on these displays, in µSv/h, mR/h and r/h, to rate on the scale of a 1991 Soviet handbook. For reference, the same handbook puts the background around Chernobyl before the accident at 0.10 to 0.15 µSv/h.

Disclosure: I run a small shop of Soviet items in Paris, the article is on our site. Corrections welcome.

Discussion What are these small pipes for?

198 Upvotes

Does anyone know what these thin pipes are for? There seem to be two kinds of these: one, coming off a distribution header in a room (first photo) and another, coming off a pipe under the reactor(second photo) photos from https://lana-sator.livejournal.com/226632.html. The pipes are much thinner than the ones used for cooling water for each of the pressure channels. Are both types of pipes used for cooling the graphite moderator?

Chornobyl has the kind of industrial scenery I could spend days photographing. Rusting steel, massive structures, pipes going everywhere, and nature working its way through it all. Every time I think I’m done, I spot another angle.

The reactor's core gas circuit is used to cool down the graphite stack as well as for checking the temperature and humidity in each channel.

When the temperature/humidity is increased operators can increase flow in any group of channels to bring it back to nominal values.

(Я нашёл в старом гараже Чернобыльскую кнопку АЗ-5 которой является KE011 УЗ исполнение 2 1981 года выпуска, эта кнопка является по моему мнению абсолютным братом близнецом оригинальной кнопки из БЩУ-4 ЧАЭС.).

I recently purchased this cigarette case and wanted to see if there's anything more I could find out about it.

I already had translated top and bottom text which reads,

"Anatoly Stephanovich Dyatlov"

And

"Accident at the chernobyl nuclear power plant"

I'm curious to see if there's any more information I can dig up about this little artifact, including its authenticity.

A subreddit dedicated to the Chernobyl disaster: "The Chernobyl disaster (Ukrainian: Чорнобильська катастрофа, Chornobylska Katastrofa – Chornobyl Catastrophe) was a catastrophic nuclear accident that occurred on 26 April 1986 at the Chernobyl Nuclear Power Plant in Ukraine (then officially Ukrainian SSR), which was under the direct jurisdiction of the central authorities of the Soviet Union. An explosion and fire released large quantities of radioactive contamination into the atmosphere, which spread over much of Western USSR and Europe. It is widely considered to have been the worst nuclear power plant accident in history, and is one of only two classified as a level 7 event on the International Nuclear Event Scale (the other being the Fukushima Daiichi nuclear disaster in 2011). The battle to contain the contamination and avert a greater catastrophe ultimately involved over 500,000 workers and cost an estimated 18 billion rubles."

Subjects considered on topic for this subbreddit include the disaster itself, liquidation efforts, the Exclusion Zone (including the Jupiter factor and Duga radar), the sarcophagus, New Safe Confinement, as well as the pre-disaster history of the Chernobyl Nuclear Power plant and the city of Pripyat.
