Computerized System for Control and Management of Radioactive Materials: Web Based Applications in Radiation Safety

L. Zhang; D. Bandyopadhyay; and S. Hoory (Mount Sinai Medical Center, One Gustave L. Levy Place, New York, NY 10029)

A computerized web based Radioisotope Inventory and Radiation Safety system for control and management of radioactive materials (RAMs) in a large medical center is reported. The system uses ORACLE II database software and runs on a centralized secured Linux server which can be accessed remotely by users via institutional Intranet. All RAMs entering the institution are logged into the system and then appropriately assigned into the files of various "Authorized Users". All transactions with RAMs such as, ordering, studies, disposals etc. are performed via the system. In case of "ordering" RAM, the system checks if the "authorized user" is approved to use the requested isotope and the activity limit. If the total activity on hand plus the requested activity do not exceed twice the approved limit, the system will approve the order. In case of short lived radioactive waste, the system will display the date and time when the waste may be disposed off as regular trash. The system maintains for each user a current ISOTOPE file, STUDY file and DISPOSAL file. The radiation safety office routinely inspects these files remotely to monitor regulatory compliance. This state of the art information system is specifically designed for large number of users and is vital for efficient operation of a radiation safety department.
