Short Abstract

OPENRED is a citizen science network for monitoring gamma radiation in Spain. Volunteers use low-cost sensors to build an open radiological map, fostering transparency and scientific literacy in collaboration with the Nuclear Safety Council (CSN).

Abstract

Public perception of environmental radiation is often characterized by a lack of information, leading to misconceptions and mistrust. To address this, the OPENRED (Open Radiation Network) project establishes a nationwide citizen science network for monitoring environmental gamma radiation in Spain. Developed through a collaboration between Spain's Nuclear Safety Council (CSN) and the Ibercivis Foundation, OPENRED has two primary objectives: (1) to generate a dense, open-access database of radiological data, and (2) to enhance public understanding and engagement with nuclear science and radiation protection principles.

The project equips volunteers from diverse backgrounds—including students, maker communities, and the general public—with low-cost, validated radiation sensors. Participants are trained to collect measurements in their local environments, contributing to a dynamic, real-time radiological map of the country. The platform includes a web portal for data visualization and analysis, as well as educational materials and engagement activities such as hackathons and collective intelligence experiments to foster a robust and informed community.

By actively involving citizens in the scientific process, OPENRED democratizes environmental monitoring and provides a valuable supplementary data source for official surveillance networks. This presentation will detail the project's methodology, from sensor validation and data quality protocols to community engagement strategies, showcasing how a regulatory agency and the public can co-create valuable environmental data and foster trust.
