Physicists Discover the Chambers of Secrets at the 16th Century Monastery in Pereslavl-Zalessky
The ancient city of Pereslavl-Zalessky, founded in 1152 by Prince Yuri Dolgoruky on the shores of Lake Pleshcheyevo, is known for its monuments of ancient Russian architecture of the 12th-17th centuries. Holy Trinity Danilov Monastery is the youngest of the surviving monasteries and was founded in 1508. Ancient documents, including floor plans, have been lost, and buildings and underground spaces require special study.
The method of muon radiography based on emulsion track detectors allows solving this problem in an accessible way, without destroying buildings during excavations. Muons are elementary particles of cosmic origin that can penetrate the soil to a depth of 2 kilometers. This feature of the propagation of atmospheric muons allows to use them for "remote" studies of the structure of the natural and industrial object on a large scale.
"
At the end of December 2021 , scientists scanned data from 22 detectors, performed a physical analysis of the results, and presented the experimental results in the form of 3D models of the buildings and the surrounding areas.

Muon radiography is used in applied research all over the world, in particular, as a promising addition to geophysical and geological methods in the analysis of volcanic, seismic and karst processes, in mineral exploration, in the field of nuclear safety for radiation monitoring of nuclear power plants, for non-destructive testing of industrial facilities.
