This is one of the main results of the "Epidemiological study on childhood cancer and proximity to radio and television transmitters," conducted by the Institute for Medical Biometry, Epidemiology and Informatics (IMBEI) of the Johannes Gutenberg University Mainz on behalf of the Federal Office for Radiation Protection (BfS).
The study included 1.959 children aged 0-14 years, diagnosed with primary leukemia between 1984 and 2003, living in the surrounding of 16 amplitude-modulated (AM) and 8 frequency-modulated (FM) transmitters (UKW-/TV-transmitters). The leukemia cases were registered at the German childhood cancer registry. Three age-, gender-, and transmitter area-matched controls per case were drawn from population registries. The study design was defined as case-control study without conducting interviews.
One of the basic elements of this study was the development of methods for the assessment of individual exposures to radio and television transmitter radiation one year before the actual diagnosis. These exposure estimates were calculated with a field strength prediction program. In a validation study, the exposure misclassification was analyzed by using field measures as gold-standard that were collected independently from the model used for field strength calculation. There was a good agreement between measured and calculated field strength.
"There is no statistical significant association between the exposure to high frequency electromagnetic fields from radio and television transmitters (RF-EMF) and childhood leukemia," says Dr Joachim Schuez, director of the study. Neither is there an assocation between exposure to RF-EMF fields and childhood leukemia when the analysis was conducted separately for AM and FM transmitters. The exposure time period was defined from 1983 to 2002, dividing the observation period into 1983-1991 and 1992-2002, representing time periods before and after the widespread use of mobile telecommunication.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
