PAAT vs Euler Gamma

PAAT was developed to enhance the capabilities of States in assessing radiation alarms triggered by a person. In most cases, the reason the person will set off an alarm is a medical treatment or diagnostic procedure involving the administration of a radiopharmaceutical. When a radiation alarm is triggered by a person, PAAT can be used by the investigating officer to conduct a simple interview and measurement. The information in the App provides assistance for the investigating officers in States in the assessment of radiation alarms caused by persons to more effectively and efficiently combat the movement of nuclear and other radioactive materials out of regulatory control at points of entry and major public events (MPE). Note: • The App does not collect any identifying personal data. • The dose estimates in the App are for standard models and should not be considered patient-specific under any circumstances. • The assessment results shall be used only for nuclear security purposes. • The App has not been extensively tested on all platforms, under all conditions. As such, users of this tool must verify all results prior to decision making.
