Resumo
This work presents an experimental study of the influence of radiation on structural health
monitoring systems based on the electromechanical impedance method using low-cost
piezoelectric diaphragms. For application of the method, the baseline was obtained without
radiation and then compared by damage indices after application of radiation. Considering
applications in nuclear power plants, the irradiation and calculation of damage indices were
performed in the range of 10 kGy–60 kGy at 10 kGy intervals. Impedance measurements were
performed in seven frequency bands between 0 and 65 kHz. The results show that, due to the
change in the impedance signatures, the damage indices values increase according to the total
applied radiation dose, which may indicate a false indication of damage. Besides, results
indicate that there are frequency bands less sensitive to radiation and a threshold can be defined
to distinguish radiation from structural damage.
