An investigation into the effect of radiation from a linear accelerator on two types of integrated circuit operational amplifiers was made. Dielectric isolation, thin film resistors and compensation diodes were used in one amplifier (μA744) . The other amplifier (μA709) was fabricated using standard methods. The μA744 amplifier, in its current stage of development, was found to be more susceptible to the effects of accumulated dose from high energy electrons than the μA709 amplifier.
