From the Big Bang to radiation protection

online lecture by Ursula Hoeppener-Kramar on 16 September 2025, 3 p.m.

Moderation: Petra Schultheiß-Reimann

The Big Bang and the period that followed brought matter into our universe. The starting materials were elementary particles, and ultimately solar systems, i.e., stars (suns) and planets, emerged. The processes used in these processes included fusion, transmutation, and nuclear fission—everything that generates energy, as well as chemical elements. Natural radioactive isotopes have existed since the formation of the elements. Humans also artificially produce other radioactive isotopes. Radioactive radiation must be measured and monitored to be used effectively in medicine and technology without causing harm.
