Due to the fact that there are more frequent questions about the radiation background in Pavilion 62 (now the International Ballet Center), previously “Atomic Energy for Peaceful Purposes”, where, according to a number of sources, an operating reactor was demonstrated, we consider it necessary to post the results of the official survey, where it is said – “No radiation anomalies were found in the building constructions. The ambient dose equivalent rate (AEDR) of gamma radiation in the surveyed premises does not exceed the dose rate in an open area by more than 0.2 μ3v / h. According to these indicators, the surveyed object meets the requirements of SanpiN 2.6.1.2523-09 (NRB-99/2009).
