Comparison of Weekly and Biweekly Generator Systems With Respect to Radiation Safety

Abstract

As a result of the rise in radiation exposure to operators of high-activity generators, we examined an alternative to the traditional single weekly generator. A system consisting of twice weekly delivery of two small generators was evaluated. Technetium-99m yields from this system were comparable to the single weekly system and radiation exposure to operators was lower. We found that the difference in operator exposure level was due primarily to physical construction of the generators rather than to weekly or biweekly delivery.
