目前我國緊急應變計畫區(EPZ)的範圍是以核電場為中心,半徑5公里的區域為範圍,但實際災害發生時輻射層的擴散常依風速及風向因素而延展超過5公里的區域,為瞭解核能事故發生時,輻射外釋可能造成的影響範圍及第三層級防災體系對核能災害之應變認知程度。本研究使用PADES模式模擬四個季節預測四天後的累積輻射劑量與即時劑量率,並依模擬結果來建立輻射劑量潛勢分佈圖;並利用問卷調查來瞭解核三廠附近之第三層級防救災體系對核能災害之應變認知程度,本問卷分成成業務機制、第三層級應變資源與能力、整備與應變等四個構面來探討,經統計分析發現鄰近核三廠的滿州鄉及恆春鎮與非鄰近核三廠的車城鄉、牡丹鄉、獅子鄉及枋山鄉對於第三層級應變資源與能力構面的看法無顯著差異,而其他三各構面之問卷結果達顯著差異。
Recently, an emergency planning zone (EPZ) was defined as existing within a 5 kilometer radius around a nuclear power plant in Taiwan. However, when a nuclear disaster actually occurs, the radiation zone would be diffused following wind velocity and direction past that 5 kilometer area. This study was undertaken to understand the influence range caused by the release of radiation and the cognitive response level for the third Level local government in a disaster prevention system. The PADES model was used to forecast the accumulate radiation dose and instant dose rates after four days of radiation release in four different seasons and to establish the radiation dose potential distribution map following simulated results. In addition, questionnaires were used to understand the cognitive response level for the third Level local government in a disaster prevention system. The questionnaire was setup with four levels, including executive mechanisms, response resources and government capabilities, preparedness, and response. The results showed that the response resources and third Level government capabilities were not significantly different between towns near nuclear power plants and towns away from nuclear power plants. However, the executive mechanisms, preparedness, and responses did show significant differences between towns near and away from nuclear power plants.
