The investigation of the oscillation pattern induced by the sterile neutrinos might determine the oscillation
parameters, and at the same time, allow to probe CPT symmetry in the leptonic sector through neutrino–
antineutrino mass inequality. We propose to use a large scintillation detector like JUNO or LENA to detect
electron neutrinos and electron antineutrinos from MCi electron capture or beta decay sources. Our calculations
indicate that such an experiment is realistic and could be performed in parallel to the current research
plans for JUNO and RENO. Requiring at least 5σ confidence level and assuming the values of the oscillation
parameters indicated by the current global fit, we would be able to detect neutrino–antineutrino mass
inequality of the order of 0.5% or larger, which would imply a signal of CPT anomalies.
