划定辐射扩散装置事件的受影响区域是应急响应中的一项重大挑战。遥感是一种很有前途的技术，可以在安全距离以外的大范围内探测和区分危险物质和无害物质。一种主要威胁-氯化铯（CsCl）粉末的遥感光谱识别出以前未被识别的发射率特征为2.96 μm (> 30%), 6.01 μm (> 20%), 7.10-7.49 μm（6- 8%）的宽特征，以及8.46(6%),8.89（11- 15%）和9.33 μm（5- 7%）的三重态。虽然2.96、6.01和7.10-7.49 μm处的特征被水蒸气等大气气体掩盖，但8.46、8.89和9.33 μm处的三重态提供了独特的光谱指纹，可以在距离较远的平台上安全地利用。
Delineating affected areas from radiological dispersal device (RDD) events is a major challenge in emergency response. Remote sensing is one promising technique for detecting and discriminating dangerous from benign materials over large areas and from a safe distance. Remote sensing spectra of one major threat—cesium chloride (CsCl) powders—identifies previously unrecognized emissivity features at 2.96 μm (>30 percent), 6.01 μm (>20 percent), a broad feature at 7.10-7.49 μm (6-8 percent), and a triplet at 8.46 (6 percent), 8.89 (11-15 percent), and 9.33 μm (5-7 percent). While the features at 2.96, 6.01, and 7.10-7.49 μm are masked by atmospheric gases such as water vapor, the triplet at 8.46, 8.89, and 9.33 _m provides a unique spectral fingerprint that can be safely exploited from platforms at standoff distances.
