Open Lecture: Radiation - Are you safe?

Save favourite

Welcome to an open lecture on radioactive materials in our everyday life. What kinde of radiation are there around us, how will it affect us and how can you protect yourself? PhD-Student Reza Salim will tell you more about this in his open lecture on Tuesday February 2nd. Welcome!

Radioactive materials are everywhere in the universe and, they have existed since the very beginning. Natural radioactive materials or radiation sources are present all around us: in the surface of the earth, in the floors and walls of buildings, in the foods and drinks we consume and in the air we breathe. In fact, our body contains radioactive materials too and we expose each other with radiation while in close contact. We are constantly being showered with the radiation from the space, in great amount. Are you safe?

We are also exposed to man-made radiation, such as X-rays, clinical radiation used in diagnostics and cancer therapy, airport security checks and such. Nuclear explosives testing, coal and nuclear power plants also release radioactive materials to the environment. Are you safe?

About Reza Salim

Reza Salim is a PhD researcher at the Dept. of Electronics Design in Mid Sweden University and the Deutsches Elektronen-Synchrotron (DESY) in Hamburg, Germany. His research areas include radiation detectors and radiation measurements. He is currently working on one of the next generation CMOS X-ray imagers, which are required for the European XFEL source. The European XFEL is currently under construction and will be in operation in 2017. It will generate ultrashort X-ray flashes—27 000 times per second and with a brilliance that is a billion times higher than that of the best conventional X-ray radiation sources.
