Working conditions at Mayak, and a lack of environmental responsibility in the past, led to additional contamination of the surrounding lake district and severe health hazards and accidents. Some areas are still under restricted access because of radiation. In the past 45 years, about 400,000 people in the region have been irradiated in one or more of the incidents.

 claim that living there poses no present-day risk, because of the decrease in the ambient radiation level over the past 50 years. They also report no problems with their health and the health of Mayak plant workers. However, these claims lack hard verification, and many who worked at the plant in 1950s and '60s subsequently died of the effects of radiation. While the situation has since improved, the administration of the Mayak plant has been repeatedly criticized in recent years for environmentally unsound practices.

Kyshtym Disaster

Working conditions at Mayak resulted in severe health hazards and many accidents. The most notable accident occurred on 29 September 1957, when the failure of the cooling system for a tank storing tens of thousands of tons of dissolved nuclear waste resulted in a chemical (non-nuclear) explosion having a force estimated at about 75 tons of TNT (310 gigajoules

). This released 740 PBq (20 MCi) of fission products, of which 74 PBq (2 MCi) drifted off the site, creating a contaminated region of 15,000-20,000 km2 called the East Urals Radioactive trace. Subsequently, at least 200 people died of radiation sickness, 10,000 people were evacuated from their homes, and 470,000 people were exposed to radiation. People "grew hysterical with fear with the incidence of unknown 'mysterious' diseases breaking out. Victims were seen with skin 'sloughing off' their faces, hands and other exposed parts of their bodies." "Hundreds of square miles were left barren and unusable for decades and maybe centuries. Hundreds of people died, thousands were injured and surrounding areas were evacuated." This nuclear accident, the Soviet Union

, is categorised as a level 6 "serious accident" on the 0-7 International Nuclear Events Scale.

Rumours of a nuclear mishap somewhere in the vicinity of Chelyabinsk had long been circulating in the West. That there had been a serious nuclear accident west of the Urals was eventually inferred from research on the effects of radioactivity on plants, animals, and ecosystems, published by Professor Leo Tumerman, former head of the Biophysics Laboratory at the Institute of Molecular Biology in Moscow, and associates.

 surmised that the information had not been released because of the reluctance of the CIA to highlight a nuclear accident in the USSR, that could cause concern among people living near nuclear facilities in the USA." Only in 1992, shortly after the fall of the USSR, did the Russians officially acknowledge the accident.

Other accidents

On 10 December 1968, the facility was experimenting with plutonium purification techniques. Two operators were using an "unfavorable geometry vessel in an improvised and unapproved operation as a temporary vessel for storing plutonium organic solution." In other words, the operators were decanting plutonium solutions into the wrong type of vessel. After most of the solution had been poured out, there was a flash of light, and heat. After the complex had been evacuated, the shift supervisor and radiation control supervisor re-entered the building. The shift supervisor then entered the room of the incident, caused another, larger nuclear reaction and irradiated himself with a deadly dose of radiation. The shift supervisor's actions are the subject of a Darwin Award nomination.

The Mayak plant is associated with two other major nuclear accidents. The first occurred as a result of heavy rains causing Lake Karachay

; over 400,000 people were irradiated.
  • In 1994, a fire resulted in a radioactive gas leak of 4% of the plant's allowed annual release.
  • In 2003, the plant's operating licence was revoked temporarily, due to liquid radioactive waste handling procedures resulting in waste being disposed into open water.
  • In June 2007, an accident involving a radioactive pulp occurred over a two-day period.
  • In October 2007, a valve failure during transport of a radioactive liquid resulted in spilling of a radioactive material.
  • In 2008, a repair worker was injured during a "pneumatic" incident, involving a quantity of alpha emitter release. The worker's hand was injured and the wound contaminated, with the worker's finger amputated to avoid further injury.
