Objective：To evaluate the MDCT ionizing radiation, this paper puts forward Suggestions on legitimated protection, the protection of health and safety. Methods：Using the related regulations of radiological methods, this paper summarizes MDCT ionizing radiation characteristics, the dose, and the damage to human body. Results：48 percent ionizing radiation received by human being is medical radiation, and dosage of computed tomography （CT） take up to 49 percent of all medical radiation,It is believed currently that CT radiation increases the possibility of cancer. Conclusion：First of all, through the various functions and scanning mode to reduce the radiation dose, and then pay attention to justify protection. Last but not the least, the more importance should be attached to the risk of excessive use of CT.
