[Analysis of the extent of harm from digitally modulated mobile telephone rays].
In the public discussion regarding the health risks of mobile phone system radiation, it is emphasized that the pulse slope of digital modulation, as defined in the GSM-Standard, will cause biological effects. In contrast, the high field strength of broadcasting and television radiation is not considered to be relevant. This paper compares quantitatively the slope of the digital GSM pulses with that of the synchronizing pulse of the television signal. The result shows clearly that the pulse spectrum of the television signal contains that of the GSM signal; in addition, the synchronizing impulse of television exhibits a much steeper slope. Considering the countrywide normal radiation intensities of television and mobile phone systems, it can be stated that the worldwide exposure to the common television signals over more than 50 years can disprove the contention of adverse biological health effects of the pulse slope of digitally modulated radiofrequency.
