Last year, the results of the survey conducted among contributors highlighted the expectation of certain changes to the map and the website . Furthermore, the introduction of several fixed markers led to confusion regarding the limited number of measurements displayed on the map.

We have therefore developed new features to allow you to navigate more easily among the results accumulated on the map , but also to quickly find the information that interests you in the educational documents that we offer.

The first change is the appearance of a new symbol on the map: a purple pin, associated with the fixed markers developed by some of you. There are currently three: one near Lille, a second in Alsace, and a third in the Paris region. The advantage of this symbol is that it will no longer obscure individual measurements, for which nothing changes. By clicking on the pin (1), you can access the contributor's name and the value of the latest measurement. Measurement recorded on this fixed beacon. By then clicking on "time profile" (2), you can view the last 400 measurements published by the fixed beacon (3). For users wishing to develop or install a fixed beacon at home, it couldn't be simpler: contact us at contact@openradiation.org and we will provide you with an API key that will allow you to associate a pin with your fixed beacon.

The second change can be found under the "The Project" menu tab, specifically in the "Newsletters" section. We have added new categories to make it easier to share documents—such as photos taken during the 2026 Contributors' Day, or tutorials on how to assemble and use the sensors and interpret measurement results. This page will continue to grow over time! So, if you are looking for specific information, don’t hesitate to stop by the website and take a look!
