United States Nuclear Regulatory Commission Order EA-05-090 has imposed increased controls on the unescorted access to and use of certain sources of ionizing radiation. At the University of Pittsburgh and University of Pittsburgh Medical Center, Oakland Campus, this would include gamma irradiators and Gamma Knives (clinical irradiators). The Order requires us to monitor access to radioactive sources and establish the trustworthiness and reliability of persons seeking unescorted access. A common plan will be implemented throughout all facilities covered by the University licenses.

The following measures have been instituted to come into compliance with the order.

Individuals deemed to be reliable and trustworthy, based upon standards established by the NRC, may have unescorted access to the gamma irradiators. All other individuals wanting access to an irradiator must be escorted and supervised by an individual who has approved access. The escort must maintain line of sight contact with the individual using the irradiator.

Trustworthiness and reliability will be determined principally by a background, employment and reference check. This is required for all current and future users who wish to have unescorted access.

An "Irradiator Access Request" form with consent to perform background checks will be required for all individuals who desire unescorted access to any irradiator.
