Looking to know the level of radioactivity around you and assess your exposure to ionising radiation? Thanks to this application, and a compatible sensor, you can measure radioactivity. You can also contribute to a citizen science project, by helping to create a collaborative data base of radioactivity measurements in the environment: OpenRadiation (published under an Open Database License). You will then be able to share your measurements using the application and view the data in the application or on the website www.openradiation.org. Create an account on the website www.openradiation.org, and obtain a compatible sensor (see the list of compatible sensors at www.openradiation.org). Activate Bluetooth under your mobile, configure your sensor to measure radioactivity, and publish your measurements. If you do not have a compatible sensor, you can always enter your measurements manually on the website or via the application. OpenRadiation currently brings together the following scientific and academic partners: IFFO-RME - training network in major educational risks -, IRSN - public expert in research and expertise on nuclear and radiological risks -, Planète Sciences – association contributing to the scientific and technical culture of young people - and SORBONNE UNIVERSITE Fablab - digital fabrication and rapid prototyping workshop, open to students, staff and the general public.
