The curve of radioactive decay of the nucleus $^{125m}$Te surrounded by stable $^{125m}$Te nuclei, which constitute a resonance Mossbauer screen, has been measured. Thorough investigations have shown that the decay of a $^{125m}$Te nucleus follows the ordinary exponential law with a half-life of $T_{1/2}=58$ days without oscillations. The fact that oscillations are present in the curves of radioactive decay of the long-lived isomer $^{125m}$Te, which has a Mossbauer level, is the result of measurement errors associated with the method.
