Ionizing radiation is one of the main risks affecting healthcare workers and patients worldwide. Special attention has to be paid to medical staff in the vicinity of radiological equipment or patients undergoing radioisotope procedures. To measure radiation values, traditional area meters are strategically placed in hospitals and personal dosimeters are worn by workers. However, important drawbacks inherent to these systems in terms of cost, detection precision, real time data processing, flexibility, and so on, have been detected and carefully detailed. To overcome these inconveniences, a low cost, open-source, portable radiation measurement system is proposed. The goal is to deploy devices integrating a commercial Geiger-Muller (GM) detector to capture radiation doses in real time and to wirelessly dispatch them to a remote database where the radiation values are stored. Medical staff will be able to check the accumulated doses first hand, as well as other statistics related to radiation by means of a smartphone application. Finally, the device is certified by an accredited calibration center, to later validate the entire system in a hospital environment.
电离辐射是影响全球医护人员和患者的主要风险之一。特别需要关注放射性设备附近的医护人员或接受放射性同位素治疗的患者。为了测量辐射值，传统的区域剂量计被战略性地放置在医院中，工作人员则佩戴个人剂量计。然而，这些系统在成本、检测精度、实时数据处理、灵活性等方面存在着重要的固有缺陷，这些缺陷已经被发现并详细描述。为了克服这些不便，我们提出了一种低成本、开源、便携式的辐射测量系统。该系统的目标是部署集成商用盖革-缪勒（GM）探测器的设备，实时捕获辐射剂量，并通过无线方式将其发送到远程数据库，在该数据库中存储辐射值。医护人员将能够通过智能手机应用程序第一时间检查累积剂量，以及与辐射相关的其他统计数据。最后，该设备由经过认证的校准中心进行认证，以便以后在医院环境中验证整个系统。
