A hazardous fluid handling system which includes a housing having a radiation shielded internal chamber disposed therein which may accommodate a container holding a radioactive fluid, one or more radioactivity detectors positioned within the shielded internal chamber in operational proximity to the radioactive fluid in the container, and a dosimeter control device electronically coupled to the radioactivity detector(s) is disclosed. The dosimeter control device is operational for determining information regarding the radioactive fluid in the container based on individual measurements received from the one or more radioactivity detectors. The hazardous fluid handling system may be integrated into a patient support platform which includes a patient stimulus apparatus, an imager proximate the patient support platform, a radiopharmaceutical fluid delivery system for infusing a radiopharmaceutical fluid into a patient, a patient monitor to be associated with the patient, and an integrated system controller.
