What is it about?
Ionizing and non-ionizing radiations are part of our daily life, and when organisms are exposed to them for a long time, they may experience their lethal or sublethal effects. For this reason, technologies have been created to quantify them. In this study, Internet of Things (IoT) was used through connecting gamma meters and a low-cost UV radiation device. The validation of this structure was performed with meters calibrated in certified laboratories. The validation results matched those obtained by the other devices, with an error of 2%.

Why is it important?
This article is important because it addresses a critical challenge: accurately measuring gamma and UV radiation in real time with a low-cost, portable, Internet-connected device. It combines open-source hardware and software technologies with IoT and cloud storage to deliver immediate and reliable data something that many commercial devices either fail to achieve or provide only at a high cost. In addition, its integration with drones makes it possible to monitor large or hard to reach areas, greatly expanding its applications in radiological protection and environmental management. This combination of affordability, validated accuracy, and remote monitoring capability makes it a unique and versatile solution for safeguarding both health and the environment.
Perspectives
Writing this article was an incredibly rewarding experience because it allowed us to turn an idea into a tangible, functional tool that can make radiation monitoring more accessible and versatile. Collaborating with colleagues who share a passion for open-source technology and practical innovation made the process both creative and technically challenging. For me, the highlight was seeing how a low-cost, portable device could achieve accuracy comparable to expensive commercial systems, while offering the flexibility to be mounted on drones for remote or hazardous areas. I hope this work inspires others to embrace accessible technology as a way to expand environmental monitoring and public safety.
