Thermoelectric devices based on the spin Seebeck effect (SSE) were irradiated with gamma () rays with the total dose of around 310 $^{5}$ Gy in order to investigate the -radiation resistance of the devices. To demonstrate this, Pt/Ni $_{0.2}$ Zn $_{0.3}$ Fe $_{2.5}$ O $_{4}$ /Glass and Pt/Bi $_{0.1}$ Y $_{2.9}$ Fe $_{5}$ O $_{12}$ /Gd $_{3}$ Ga $_{5}$ O $_{12}$ SSE devices were used. We confirmed that the thermoelectric, magnetic, and structural properties of the SSE devices are not affected by the -ray irradiation. This result demonstrates that SSE devices are applicable to thermoelectric generation even in high radiation environments.
