Acquisition of consecutive ultra-short interval measurements with a radiation detector serves in detecting anomalies in the ambient environment, potentially caused by hidden radioactive material. An anomaly is defined as the contribution of a man-made radiation source to the measured signal. In this paper a new methodology is presented and tested on detecting anomalies in various radiation signals...
