Comprehensive Approach for Monitoring and Analyzing the Activity Concentration Level of PET Isotopes

A comprehensive approach for measuring and analyzing low concentration levels of positron emitter isotopes is introduced. The solution is based on a Continuous Air Monitoring Sampler (CAMS), Stack Monitoring System (SMS) and software package. Positron Emission Tomography (PET) is a major tool for both, biochemical research and non-invasive diagnostics for medicine imaging. The PET method utilizes short half life β+ radioisotopes that are produced in cyclotron sites built especially for this purpose. The growing need for β+ isotopes brought about a commonly wide use of cyclotrons next to populated areas. Isotopes production involves two possible radiation hazards deriving from the activity concentration; one refers to the nearby population by the activity released through the ventilation system and the other refers to the personnel working in the nuclear facility. A comprehensive system providing solution for both radiation hazards is introduced in this work
