We study in this research the phenomenology of $\mu\to e\gamma$ decay in ascenario of the class of extended models with non-sterile right-handed (RH)neutrino at electroweak (EW) scale proposed by P.Q. Hung. Field content of thestandard model (SM) is enlarged by introducing for each SM fermion acorresponding mirror partner with the same quantum numbers beside oppositechirality. Light neutrino masses are generated via the type-I see-saw mechanismand it is also proved to be relevant with low energy within the EW scale of theRH neutrino masses. We introduce the model and derive branching ratio of the$\mu\to e\gamma$ decay at one-loop approximation with the participation of Wgauge boson, neutral and singly charged Higgs scalars. After that we setconstraints on relevant parameters and predict the sensitivities of the decaychannel under the present and future experiments.
