Human begings living in the world surrounded fully of radition been mentioned for a long time. There would be no magic finding as X-ray developing so quickly and spreading so broadly throughout the scientific world. As the report pronounced, 90% of radiation were used in medical field, especially the more application in the clinical care. Owing to more chance to contact the radiation, majority of nurses may feel anxious, and even reject to the closing care of patient. The knowledge, about attitude and behavior of facing radiation, may help nurses to have a good performance of radiation protection. The following research consisted of 138 nurses working in the medical teaching hospital of central section and helps us to correct information about the clinical workers, awareness of radiation protection and procedure to prevent the wrong protecting behavior were done. We hope that this paper will give teachers and pre-workers,to lessen the unnecessary fear of X-ray and to ensure the clinical workers' safety while they are in contact the radiation.
