作为其年度大范围许可证辐射防护计划审查的一部分，德克萨斯大学休斯顿健康科学中心辐射安全计划发现，尽管在转授权人层面有效实施了库存控制和监测机制，但不存在一种方法来证明在机构层面遵守集体大范围许可证拥有限制。为了解决这一缺陷，修改了辐射安全方案数据仓库系统，并创建了一个自动摘要报告，显示集体次级许可证持有人的最大拥有授权。但该报告没有以关键利益攸关方容易理解的方式有效地提供摘要信息，因为数据没有参考集体机构拥有限制。因此，创建了汇总报告的图形版本，其中，对于所拥有的每种同位素，显示了集体机构限制，沿着所有单个次级许可证持有人的最大拥有限制和当前数量的总和。这个简单的图形用于有效地将机构辐射源库存的当前状态传达给辐射安全委员会、执行管理层和州监管官员。这一努力有助于简化有时很复杂的放射源清单控制过程，并促进了随后的方案审查。在未来，该方法有望帮助辐射防护计划预测何时可能需要广泛的许可证修订，以适应操作的变化。
As part of its annual broad scope license radiation protection program review, the University of Texas Health Science Center at Houston radiation safety program discovered that although inventory control and monitoring mechanisms were being effectively implemented at the sublicensee level, a method did not exist to demonstrate compliance with collective broad scope license possession limits at the institutional level. To address this shortcoming, the radiation safety program data warehouse system was modified, and an automatic summary report showing collective sub-licensee maximum possession authorizations was created. But this report did not effectively present the summary information in a manner that key stakeholders could readily comprehend, as the data was not referenced to collective institutional possession limits. So a graphic version of the summary report was created wherein, for each isotope possessed, the collective institutional limit was displayed, along with the totals of all the individual sub-licensee maximum possession limits and current amounts on hand. This simple graphic served to effectively communicate the current status of the institution’s radiation source inventory to the radiation safety committee, executive management, and state regulatory officials. The effort has served to simplify the sometimes-complicated source inventory control process and has facilitated subsequent program reviews. In the future, the method is expected to assist the radiation protection program in anticipating when broad license amendments may be needed to accommodate operational changes.
