| Abstract ---Radiology 
              incident has been a great threat to Taiwan. Any leakage of radiation 
              can lead to major casualties. We wonder whether emergency department 
              been well prepared if this situation occurred here. Because radiation 
              is not physically detectable, it’s difficult for a primary physician 
              to determine the severity of the victim. Numbers showed on the survey 
              meters may not be compatible with the dosage the patient has exposed. 
              Three ways of radiation-induced injury may occur: external irradiation, 
              contamination with radioactive materials, and incorporation of radioactive 
              material into tissues, cells, or organs. The different causes for 
              radiation-induced injury may result in different modes of emergent 
              management. The standard emergency protocols of advanced cardiac 
              life support (ACLS), advanced pediatric life support (APLS), and 
              advanced trauma life support (ATLS) should always take care first 
              over treating the effects of radiation because of concomitant clinical 
              conditions. The medical stability of the patient should be ensured 
              before concentrating on the radiation-related clinical issues. Lymphocyte 
              count in 48 hour is very important predictor of prognosis. We can 
              minimize radiation exposure through decrease the amount of time 
              the victims spend near the source of radiation. It is also essential 
              to increase distance and shielding between radioactive sources. 
              Four levels of response to radiation event in Taiwan. Depending 
              how serious the radiation has been leaked, the impact on society 
              greatly differs. |
