Radon Dosis
The Radon Dose app calculates the radiation dose caused by the radioactive noble gas radon. As a starting point for the calculation, the app uses information on the activity concentration in becquerel per cubic metre (Bq/m3) as well as the length of stay, with the option of distinguishing between place of work and place of residence. The result of the calculation is given as an annual radiation dose in millisieverts (mSv). The app calculates the radon dose using the specified data on the basis of scientific assumptions and models.

Comparative values for radiation exposure - e.g. the X-ray image of a tooth - help to better categorise the results. At the same time, the app provides users with tips on what they can do in the event of elevated levels.
Curious Marie
The Curious Marie app calculates personal radiation exposure. Users can enter data in four categories that have an influence on individual radiation exposure: place of residence, medical examinations, air travel and smoking habits.

In order to better understand and assess the personal radiation dose, Curious Marie also contains explanatory background information. Those who want to delve deeper into the subject can test and expand their knowledge on the topics of nuclear physics, radiation and radiation protection with a quiz and learning videos.
