“…As demonstrated in the literature ( Kundi and Hutter, 2009;Sage and Carpenter, 2009;Khurana, 2008;BIOINITIATIVE REPORT, 2007;Cherry, 2006;Cherry, 2007;Hardell and Sage, 2007), exposure to electromagnetic radiation of low intensities for long periods of time is a determinant for the aggravation and the emergence of diseases in humans. Studies point to observations of environmental carcinogens as an alert to the scientific community .…”

“…Mobile phones, digitally enhanced cordless telecommunication (DECT) phones, routers and others belong to a group of wireless telecommunication sources which have caused a dramatic increase in environmental levels of electromagnetic radiation [1,2]. All these sources emit radiation with different characteristics in a wide spectrum of frequencies ranging from 0.9 to 2.5 GHz.…”

Wireless telecommunication sources working with frequencies ranging from 0.9 to 2.5 GHz are still increasing rapidly. Among these are also digitally enhanced cordless telecommunication (DECT) phones which emit only a weak radiation when an active DECT base and its handset are separated from each other. To address this topic, we investigated the cellular effects of DECT base radiation and its possible compensation by specially designed novel resonance devices. Connective tissue fibroblasts (L-929) were exposed to the radiation of an active commercially available DECT base ± single resonance devices or combination of them. Unexposed cells in another incubator without any DECT base radiation served as corresponding controls. Cell vitality was checked by measurement of the enzymatic activity of mitochondrial dehydrogenases by the color change of the sodium salt 2,3-bis[2-methoxy-4-nitro-5-sulfo-pheny]-2H-tetrazolium-5-carboxyanilide (XTT).The results clearly demonstrate that exposure to DECT base radiation caused a significantly reduced cell vitality which was accompanied by marked morphological changes in the cells such as intracellular vacuolization, rounding and detachment. Approximately 15% of the reducing potential was related to microwave-related warming. Reduction in cell vitality after DECT base radiation exposure was partially neutralized by use of one of the novel resonance devices alone or in combination. Especially resonance device type A-1 was very effective and its potential for neutralization could be increased to 95% by additionally using two crossed resonance devices type RD-B with their plus end directed towards the cells.

“…A key advantage of this study was the use of a mailed questionnaire, which allowed participants to verify responses by checking telephone bills (Kundi 2010). Recall bias could have increased risk estimates in positive studies if more cases than referents believed mobile phone use to be the cause of their brain tumour (Sage and Carpenter 2009;Hepworth et al 2006). Studies of mobile phone use have been difficult to compare and interpret due to methodologic differences and the paucity of rigorous design.…”

“…No studies on mobile phone use and risk of brain tumours have been planned for the U.S. that are comparable in size and detail to the COSMOS. The thermal radiation emitted during average mobile phone use is low and generally is not believed to cause direct DNA damage or any other significant deleterious biologic effects on the brain (Wainwright 2000;Johansen et al 2001;Sage and Carpenter 2009;NRPB 2003). However, questions remain regarding the non-thermal effects of non-ionising radiation from mobile phones.…”
