Entering the cave is completely prohibited from being near ‘Chelyabinsk-40′ nuclear complex, also known as ‘Mayak’ (’Lighthouse’), where on September 29 1957 an explosion of nitrate and dry acetate occurred in a deposit of highly radioactive waste and produced a release of 20 million Curies of radioactivity into the atmosphere. The explosion was caused by a failure of the cooling system of the tank.
Over the past 45 years, about half a million people in the region have suffered the consequences of the incident, exposing them to up to 20 times the radiation suffered by the victims of Chernobyl.
“Sometimes, when you practice a skill that you’re trying to improve, you might feel like you’re actually getting worse over time, instead of better.

This means that you might start feeling like you’re suddenly making a lot of mistakes. In reality, however, you were likely already making those same mistakes beforehand. The difference is that you’re now good enough to actually realize when you’re making those mistakes, whereas earlier you simply didn’t have the necessary proficiency which is required in order to be able to notice it.”
