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.

Track magnetic fields near you. A warning beep will be activated to warn you. The app detects ferromagnetic metals using the iPhone's built-in compass feature. Also works as Electrosmog (EMP) detector. Detect many kinds of home appliances that create radio-frequency EMF. For example:plugs,cell phones,routers, baby monitors, doorbells, intercom systems,night alarm clocks, electronic appliances , electrical wire, antennas. You can check the limit allowed in the "Radio-Frequency Guidelines - for continuous and prolonged exposure" in the instructions button of this app. The higher measures of magnetic fields are stored. Not only does it help you identify potential sources of harmful EMF, but it also provides guidelines on the allowed limit for continuous and prolonged exposure, helping you make informed decisions about your environment. Plus, it stores the higher measures of magnetic fields with a date stamp for each event, allowing you to monitor your exposure over time. Magnetic fields are measured in nT (nanoTesla) and/or milligauss (mG). Customize your screen colors, calculate the magnetic force in nano tesla (nT), and store your records for future reference. Don't leave your health to chance. Take charge of your surroundings and shield yourself and your loved ones from harmful EMF radiation. Take control of your environment and protect yourself and your loved ones from harmful EMF radiation. Health is our most important asset. +++ FEATURES: -Track high magnetic fields and when has it been measured. -Table guide "Radio-Frequency Guidelines - for continuous and prolonged exposure". -Warning beep near focus emissions. -Magnetic force is calculated in nanoteslas ( nT ) -Record your readings with a date stamp of each event. -Store your records. -Change colors of your screen.
