The Chernobyl "Suicide Squad" were three plant workers—Alexei Ananenko, Valeriy Bezpalov, and Boris Baranov—who volunteered to dive into the flooded basement of the exploded reactor in 1986 to manually open valves, drain water, and prevent a catastrophic steam explosion that could have released even more radioactive material across Europe. Though the mission was extremely dangerous and became legendary, reports that they all died quickly from radiation poisoning are largely a myth; they survived, although their heroic actions were critical, and they were later honored as Heroes of Ukraine.
Three courageous men, knowing full well that this was a death mission, volunteered. Alexi Ananenko, Valeri Bezpoalov, and Boris Baronov put on a brave face and their scuba gear. They then dove into the contaminated water and succeeded in releasing the valve.

His body was never found, and it is presumed that he is entombed under the remnants of the circulation pumps. A monument to Khodemchuk was built into the side of the Sarcophagus' interior dividing wall, east of the pump hall where he died.
The reality is much more positive than the myth, with all three men escaping such a grisly fate. Indeed, Alexei Ananenko and Valeri Bespalov are believed to be both still alive as of 2024, while Boris Baranov lived until 2005 when he passed away from heart disease.
The three men would live longer than a few weeks and none would succumb to ARS, as modern myth would have you believe. As of 2015, it was reported that two of the men were still alive and still working within the industry. The third man, Boris Baranov, passed away in 2005 of a heart attack.
Over time, commercial divers may develop an increased risk of certain cardiac conditions, including arrhythmias, hypertension, and in some cases, structural heart changes. Ear injuries are among the most common diving-related conditions and can become serious: Inner ear barotrauma can lead to permanent hearing loss.
Yes, Chernobyl is still highly radioactive in many areas, especially near the damaged reactor, but radiation levels vary significantly; some parts of the exclusion zone have contamination low enough for potential limited agriculture, while a 2025 drone strike damaged the New Safe Confinement (NSC) structure, raising concerns about long-term containment, although immediate levels stayed stable as the NSC's function is to contain the original sarcophagus's radioactive material, not the entire zone.
The dangerous part was that the basement was also submerged in extremely radioactive water. The men went into the basement in diving gear and took flashlights. It is said that as they were searching for the valves, their flashlights went out, and they had to search for these valves in complete darkness.
Lots of people from the control room survived, including the operators Stolyarchuk and Kirschenbaum. There's a survivor who was very close to the reactor, his name is Oleg Genrikh . There are also lots of survivors that were elsewhere in the reactor building, the vent block, or the turbine hall.
The "heroes of Chernobyl" refer to the many individuals who risked their lives during the 1986 disaster, notably Soviet inorganic chemist Valery Legasov, who led the scientific response and presented the truth internationally, and the "suicide squad" divers (Alexei Ananenko, Valeri Bespalov, Boris Baranov) who manually drained water from the reactor basement to prevent a steam explosion. Other heroes include firefighters like Volodymyr Pravyk, who were the first responders, and countless liquidators (cleanup workers) who worked under extreme conditions.
Alexander Yuvchenko was on duty at Chernobyl's reactor number 4 the night it exploded on 26 April 1986. He is one of the few working there that night to have survived. He suffered serious burns and went through many operations to save his life, and he is still ill from the radiation.
The reactor crew could ascertain only that the radiation levels were somewhere above 0.001 R/s (3.6 R/h), while the true levels were vastly higher in some areas. Because of inaccurate low readings, reactor crew chief Aleksandr Akimov assumed that the reactor was intact.
But the control rods had a design flaw that now proved deadly: their tips were made of graphite. The graphite tips attached to a hollow segment one meter (3.28 feet long), which attached in turn to a five-meter absorbent segment.
Gorbachev's tone throughout the speech was bitter toward the West. He offered not a word of self-criticism or apology to the Western European nations exposed to radiation from the accident. His remarks on testing were a lame effort to divert Western attention from the Soviet performance during the accident.
The reason why the EPS-5 button was pressed may never be known, whether it was done as an emergency measure or simply as a routine method of shutting down the reactor upon completion of the experiment.
A dose of 100 to 200 rad delivered to the entire body in less than a day may cause acute radiation syndrome (ARS), but is usually not fatal. Doses of 200 to 1,000 rad delivered in a few hours will cause serious illness, with poor prognosis at the upper end of the range.
In 2011, the director of the Chernobyl power plant, Ihor Gramotkin, was asked when the area would again be inhabitable. He responded, “At least 20,000 years” (Harrell and Marson).
Surprisingly it is possible to make a tour to the former Nuclear Reactor at Chornobyl. For about 195 EUR a Person you will get picked up at your hotel in Kiev for a full day tour including lunch ( Guarantee radiation free).
In a landmark 2023 study, the research team discovered evidence of genetic differences between canine populations living in two distinct areas of the CEZ, suggesting Chernobyl's dogs could have adapted to chemical and environmental exposures over generations.
The 🤙 hand signal (shaka sign) isn't a standard core scuba signal but often means "hang loose," "cool," or sometimes "decompression" (especially in Europe), though the official signal for that is usually a fist with the pinky up, while the "OK" sign (thumb and index finger form a circle) is the universal "Are you okay?" or "I'm okay" in diving, with the 🤙 being a more casual, culture-influenced gesture among divers.
The 120 Rule in scuba diving is a simple guideline for estimating your No Decompression Limit (NDL) for recreational air dives: 120 minus your depth in feet equals your maximum bottom time in minutes (e.g., 120 - 60ft = 60 min). It helps manage nitrogen absorption, keeping dives safer by suggesting shorter times at greater depths to avoid decompression sickness, but it's a conservative estimate, best for shallower dives (under 100 ft), and doesn't replace dive computers or tables for complex dives (like those using Nitrox).
