After World War II ended, prisoners of Gulag started building the secret City-40 where the Soviets produced plutonium
In 1945, around 40,000 prisoners were taken from 12 labor camps and together with nuclear scientists, began construction of the underground nuclear facilities. The Russian convicts agreed to work there in exchange for a lesser sentence. They were given the option to either work 25 years hard labor in Siberia or 5 years underground in City-40. The first nuclear reactor was built in 18 months and additional nearby facilities would be constructed around the area later named Ozersk. Little did the construction workers know that they were signing themselves up for a death sentence. No one would live beyond five years having exposed themselves to such great levels of radiation.
As if you've seen "any others" back then and are able to compare. Fat propaganda is so fat nowadays.

First reactor has been started June 19, 1948. Where did the radioactive material come from before that day?
> To this day, Ozersk is largely contaminated
How contaminated actually? Who did the measurements? When? With what equipment? Boredpanda didn't care to cite any reliable sources. Neither did you.
Why don't you talk about "releasing large amounts of radioactive material" over Hiroshima and Nagasaki? They didn't even get "shops abundant with food".
