Abstract
The massive open online course "Essential radiochemistry for society" represents a modern form of education. Due to its attractive design, varied content and interactive nature, it has the potential to appeal to various interest groups.
Thematically, the course is divided into five weeks: Radiochemistry for the environment, health, industry, nuclear energy and society. In addition to radiochemistry and nuclear chemistry, which are the basis of the course, direct connections can be found to biology, physics, ecology, art and culture.
The course is comprehensive; a participant can study only selected chapters or the entire course independently. Recommendations and tips for effectively using the course in classes have been compiled for teachers and lecturers.
