Was the increase in cancer caused by the radioactive fallout from Chernobyl or could it be explained by other circumstances? New research from Linköping University provides scientific support for the Chernobyl connection.
"This issue is important because the indicated increased risk may come to influence the prevailing exposure limits for the population. Enhanced knowledge of the risks entailed by radioactive radiation is key to work for radiation safety and makes it possible to prevent diseases," says Martin Tondel, a physician and researcher in environmental medicine who will soon be defending his doctoral dissertation Malignancies in Sweden after the Chernobyl Accident in 1986.
In two studies using different methods, Martin Tondel has shown a small but statistically significant increase in the incidence of cancer in northern Sweden, where the fallout of radioactive cesium 137 was at its most intense.
The cancer risk increased with rising fallout intensity: up to a 20-percent increase in the highest of six categories. This means that 3.8 percent of the cancer cases up to 1999 can be ascribed to the fallout. This increased risk, in turn, is 26 times higher than the latest risk estimate for the survivors of the atom bombs in Hiroshima and Nagasaki, whose exposure was many times higher.
The increase in Tondel's studies came a remarkably short time after the disaster, since it is usually assumed that it takes decades for cancer to develop. The dissertation discusses the interpretation of the research findings from the perspective of the theory of science.
The conclusion is that there is scientific support for a connection between the radioactive fallout and the increase in the number of cancer cases.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
