Simultaneous environmental\/intrinsic background suppression using a portable compact LaBr$_{3}$:Ce\/NaI:Tl phoswich detector

Experimental background energy spectra acquired through 10-hour measurements using different detectors: the standalone LaBr$_{3}$:Ce detector (black) and the phoswich detector (red).本数据集包含通过采用两种不同探测器开展10小时测量所获取的实验本底能谱：分别为独立式溴化镧铈（LaBr₃:Ce）探测器（对应黑色曲线）与复合闪烁探测器（phoswich）（对应红色曲线）。
