An Inexpensive System for Increasing Security and Accountability of Self-Contained Irradiators
The University of Cincinnati is licensed by the state of Ohio to possess a Gammacell 40 irradiator for irradiation of clinical samples, testing, and research and development, including the irradiation of small animals, cells, and tissue. In the fall of 2003, a set of keys for the Gammacell 40 irradiator was misplaced for several days. The misplaced key set included an irradiator room door key and an irradiator operation key. At the time the keys were misplaced they were being stored in a drawer. Using an "honor system," approved operators signed up for irradiator use and possession of the keys. Operators were expected to return the keys promptly after using the irradiator. The keys' storage drawer was located in a laboratory remote from the irradiator room under the control of and near the office of an authorized user designated as responsible for management of the irradiator keys. During the investigation of the misplaced keys, it became apparent that improvements to irradiator key control and accountability were needed. Options were investigated. The option selected was an inexpensive key retainer system. The key retainer system was installed and its use implemented in January 2004. The key retainer system has improved irradiator key control and accountability, along with improving irradiator room security and irradiator use accountability.
