摘要

日本福島核災經驗，核能電廠輻射洩漏災變發生，汙染擴散距離長達數十公里時，對應變決策至關重要之特定輻射核種成分與活度調查，傳統作業必須包括：抽取樣本、實驗室運交、精密測量以及資料運算等四個步驟。面積廣大時，執行上述作業步驟費力費時，與掌控事故發展之分秒必爭要求，無期待可能性。雖然可以運用移動式環境偵測車輛，將高精密之實驗裝備運送至事故現場，就地實施取樣及輻射核種分析，但這類裝備主要使用高精密偵投器及電子週邊，僅能於嚴格控制之溫度與環境下才可發揮正常功能，兼以設備笨重、價格昂貴、高維護成本、有限之數量及妥善率， 並不足以應付瞬息萬變、複雜多樣之核輻射事故情境。本研究成果係針對上述缺點，根據行政院核能研究所獨特之脈衝分析晶片發明專利，開發一種成本低廉、輕巧省電、使用碘化納偵檢器之低成本能譜分析模組，搭配智慧型手機，適用於大量生產與分發使用，有效地解決大面積汙染調查所需之裝備數量、輸運及妥善率問題。

並列摘要

Experiences gained from Japan Fukushima nuclear accidents have told us that conventional SOPs are not applicable to urgent, large area radioactive isotopes survey. Although we can count on mobile radiological laboratories which are delivered with sophisticated measurement and data manipulation equipments, however both their quantity and viability are highly limited and they are still far from enough under emergent conditions. The lnstitute of Nuclear Energy Research has developed a simple smart phone radionuclide survey meter based on her unique pulse analysis chip. Thanks to great technology progress on massive low cost smart phone and Nal (Tl) scintillation detectors, we may get all necessary tasks be done on site simultaneously such as, multi-channel analysis, nuclide identification, activity measurements, GPS positioning, and long range wireless transmission required for large area survey simply by finger tip on smart phone touch screen of this light weight equipment.
