Lecture in the series "Brötchen und Borussia" by Prof. Dr. Armin Lühr (TU Dortmund)
Radiation has always been fascinating. The very first Nobel Prize in physics was awarded to Röntgen for the discovery of X-radiation, which was still a mystery at the time. And shortly thereafter, Nobel Prizes followed, for example, for Becquerel and Curie on radioactivity.
But where does so much interest in radiation come from? Radiation is actually bad for man and nature - isn't it? One thing is clear; without radiation we would be absolutely in the dark. But that wouldn't be the main problem, because without radiation we wouldn't exist at all.
The truth is that we are all constantly exposed to different types of radiation, which comes from the natural environment, technical devices or medical treatments. It is therefore necessary to understand how different types of radiation affect people and, in particular, the genetic material in our cells - the DNA - in order to use this effect responsibly and for the benefit of mankind. In medicine, for example, X-rays in small doses allow millimeter-precise insights into internal anatomy, the administration of radiopharmaceuticals allows the location of tumor foci in patients, and ion beams at half the speed of light allow the highly precise fight against cancer.
So is everything half as bad after all? Then we should talk again about the next intercontinental flight.

Location & approach
The campus of the Technical University of Dortmund is located near the freeway junction Dortmund West, where the Sauerland line A45 crosses the Ruhr expressway B1/A40. The Dortmund-Eichlinghofen exit on the A45 leads to the South Campus, the Dortmund-Dorstfeld exit on the A40 leads to the North Campus. The university is signposted at both exits.
The "Dortmund Universität" S-Bahn station is located directly on the North Campus. From there, the S-Bahn line S1 runs every 20 or 30 minutes to Dortmund main station and in the opposite direction to Düsseldorf main station via Bochum, Essen and Duisburg. In addition, the university can be reached by bus lines 445, 447 and 462. Timetable information can be found on the homepage of the Rhine-Ruhr transport association, and DSW21 also offer an interactive route network map.
One of the landmarks of the TU Dortmund is the H-Bahn. Line 1 runs every 10 minutes between Dortmund Eichlinghofen and the Technology Center via Campus South and Dortmund University S, while Line 2 commutes every 5 minutes between Campus North and Campus South. It covers this distance in two minutes.
From Dortmund Airport, it takes just over 20 minutes to get to Dortmund Central Station by AirportExpress and from there to the university by S-Bahn. A wider range of international flight connections is offered by Düsseldorf Airport, about 60 kilometers away, which can be reached directly by S-Bahn from the university's train station.
The facilities of TU Dortmund University are spread over two campuses, the larger Campus North and the smaller Campus South. Additionally, some areas of the university are located in the adjacent "Technologiepark".Zum Lageplan
