Abstract
Introduction: London bombings on July 7, 2005 presented serious difficulties for medical response, moreover, if a dirty bomb attack had occurred in an underground train, it would have been more difficulties to cope with. Based on this possibility, it is critical to take strategies on medical response to dirty bomb attacks in underground transport systems into account beforehand. Method: In the Windows 10 operating system, visual studio 2019 environment, we used C ++ language to develop a system that can simulate the process of nuclear or radiological emergency medical rescue based on discrete event simulation, mainly considering the designs of professional rescue groups, staffs’ energy consumption, injured and uninjured persons on site, and competence value of key staffs.Results: In the scenario of a subway dirty bomb terrorist attack causing 2.6 casualties per minute and 208 casualties in total, the manpower needed for the emergency medical response were 5 pre-triage groups, 7 contamination triage groups, 23 decontamination groups, 5 first-aid groups, and 12 comprehensive treatment groups. Besides, 5 first-aid groups and 45 decontamination groups were added to implement on-site rescue. The total number of actual participants in the medical response should be about 337. More than 337 PPE should be prepared.Conclusion: We designed and constructed a simulation system, and used it to explore the medical response preparation strategies for subway terrorist dirty bomb explosion, including preparation of sufficient staffs and equipment, consideration of the rotation needs of the staffs, and perception of real-time situation on site and agile command, especially obtained the prediction method of staff and equipment resources for specific disaster background, which could provide constructive references for the security protection of urban subway systems in the future.
