The radiation safety culture of those working in university open-source radioactive material laboratories was assessed by conducting both surveys and behavioral observations. Baseline results (n = 82, 89% response rate) of assessed safety culture categories indicated safety practices and safety compliance were the most in need of improvement. Specific training based on these results was provided to laboratory members at Princeton University, with creative signage and a safety newsletter posted in and around laboratories for reinforcement, in a targeted effort to improve the radiation safety culture. Signage posted utilized pop cultural memes and other engaging graphics designed to raise awareness of appropriate safety practices and the minimum laboratory attire expected while working in radioactive material laboratories. Postintervention results (n = 38, 43% response rate) indicated improvement in 4 out of the 10 safety culture indicators considered as well as fewer instances of improper safety practices. Collaborative techniques and increased communication between researchers and radiation safety staff appear to have initiated an improvement in the radiation safety culture in open-source radioactive material laboratories at Princeton University.

开源大学实验室中改善辐射安全文化的一种混合方法。

通过开展调查和行为观察，对在大学开源放射物质实验室工作的人员的辐射安全文化进行了评估。评估的安全文化类别的基线结果（n = 82，响应率89％）表明，最需要改进安全实践和安全合规性。根据这些结果，对普林斯顿大学的实验室成员进行了专门培训，并在实验室内和实验室周围张贴了创新的标牌和安全通讯，以加强辐射安全，从而有针对性地致力于改善辐射安全文化。张贴的标牌利用流行的文化模因和其他引人入胜的图形设计，旨在提高人们在放射性物质实验室工作时对适当安全实践和最低预期实验室着装的认识。干预后的结果（n = 38，响应率43％）表明，在所考虑的10个安全文化指标中，有4个指标得到了改善，并且发生了不正确的安全实践案例。普林斯顿大学开放源放射物质实验室的协作技术和研究人员与辐射安全人员之间日益密切的交流似乎已开始改善辐射安全文化。
