A System for the Automatic Monitoring and Safe Disposal -of Short-lived Radioactive Gaseous Compounds from Hot-cells in a PET Facility

摘要

A novel automated system for the detection and disposal of radioactive gases emitted within the wails of a hot-eell is described. The system has been designed and installed at the Nuclear Medicine Division's PET Unit of the National Ca.ncer Instituteof Milan (Italy) Basically, a radiation detector monitors the air exhausted from the hot-cell, which is normally released through the hospital mam chimney. Beyond a selected threshold of radioactivity concentration, the ait flow is automatically conveyedto a buffer tank. A set of measures to ensure radiation safety to the chemist is also repotted.
