Abstract
We consider the experimentally detected XENON1T excess of electron recoil events in the energy range from 1 to 7 keV in terms of the phenomenological model with three active and three decaying sterile neutrinos. Estimations of the decay parameters for the radiative decay of a Majorana sterile neutrino due to the magnetic dipole transitions into other neutrino states are made. The analytical expressions for the transition and surviving probabilities for different neutrino flavors are obtained with consideration of the decaying sterile neutrinos contributions, and the graphs of the dependences of these probabilities are presented.
