The quantum Zeno effects were studied critically for indirect measurements. The excited state of the two-level system was found to decay to the ground state by emitting light. The investigation of a model of indirect measurements of Zeno and anti-Zeno effects in spontaneous decay of two-level atom show the taking place of the quantum zeno effect even if the detector of a photon excitation emitted from the atom does not cover the full solid angle. The results confirm that the survival probability of the decaying state is not affected by the successive indirect measurements.
