Ionising radiation occurs in nature and our environment due to natural sources as well as in wide-spread applications in science, technology and medicine.
After being instructed our students can do the experiments themselves under supervision of a special qualified teacher. The most interesting experiments are about random variations of counting rates, distinguish the three different types of radiation by absorption measurements, determine the half life of Ba-137 and the deflection of beta-particles in a magnetic field.
Our cloud chamber is a special highlight. Here we can visualise even the natural radiation in a spectacular way and you can easily take pictures of the tracks of the radioactive particles.
