Abstract :The commercial used the 555 single timer and the 741 operational amplifiers insert ignore into journalissuearticles values(op-amp); were investigated under the gamma-ray radiation of the Co-60 source. The maximum total doses were used 2 kGy and 4 kGy to irradiate. The abnormal behavior in the 555 single timer circuit frequency was observed, which decreased from 202 to 195 Hz at 744 Gy gamma-ray radiations. In the results of 741 opamp circuit, the amplitude signal of the 741 op-amp shows a maximum value of -0.054 dB at 4 kGy gamma dose and its slew rate decreases from 4 to 0.65 V/µs. The 555 single timer has two pn junctions and these cause that the 555 single timer is easily affected by the gamma radiation. Consequently, the integrated circuits must be tested to determine their resistance limits in the radiation environments.
