This paper describes new spectrometric techniques for Homeland Security Radiation Monitoring, which can solve the problem of "innocent alarms" in pedestrian monitoring due to medical radionuclides. At airports or seaports, when large crowds are checked, innocent alarms are frequently caused by medical radionuclides which are administered to patients for various diagnostic or therapeutic purposes. For every such alarm a laborious and time consuming secondary inspection procedure is required, which impedes the flow of traffic and annoys front line officers as well as innocent passengers. The results of an extended test at the Vienna International Airport, where over one million passengers have been screened up to now, clearly show, that this problem can be solved using spectrometric radiation portal monitors (SRPM). More than 95% of the innocent medical alarms have been dynamically identified as "green alarms" without the risk of masking Special Nuclear Materials (SNM) or other illicit radionuclides.
