In 1993 the University of Extremadura initiated the design, construction and management of the Radiological Alert Network of Extremadura (RAREx). The goal was to acquire reliable near-real-time information on the environmental radiological status in the surroundings of the Almaraz Nuclear Power Plant by measuring, mainly, the ambient dose equivalent. However, the phased development of this network has been carried out from two points of view. Firstly, there has been an increase in the number of stations comprising the network. Secondly, there has been an increase in the number of monitored parameters. As a consequence of the growth of RAREx network, large data volumes are daily generated. To face this big data paradigm, software applications have been developed and implemented in order to maintain the indispensable real-time and efficient performance of the alert network.

In this paper, the description of the current status of RAREx network after 30 years of design and performance is showed. Also, the performance of the graphing software for daily assessment of the registered parameters and the automatic on real time warning notification system, which aid with the decision making process and analysis of values of possible radiological and non-radiological alterations, is briefly described in this paper.

1993 年，埃斯特雷马杜拉大学发起了埃斯特雷马杜拉放射警报网络 (RAREx) 的设计、建设和管理工作。目标是通过主要测量环境剂量当量来获取有关 Almaraz 核电站周围环境辐射状况的可靠的近实时信息。然而，这个网络的阶段性发展是从两个角度进行的。首先，构成网络的站点数量有所增加。其次，监测参数的数量有所增加。由于 RAREx 网络的发展，每天都会产生大量的数据。面对这种大数据范式，

本文描述了 RAREx 网络经过 30 年的设计和性能的现状。此外，用于注册参数的日常评估的图形软件和自动实时警告通知系统的性能，有助于决策过程和分析可能的放射学和非放射学改变的值，在本文中进行了简要描述纸。
