For those interested in finding a physically noninvasive, and non-equipment method to test for RF –EMF sensitivity to WIFI, smart meters, cell phones and other electronic wonders, a recent Austrian study may point  the way.

 

A recent Austrian study has shown how a few institutionally acceptable set of stress biomarkers in Saliva  are reactive after exposure to very low levels of  RF radiation from Cell phone transmitter.  A pubmed search reveals  these biomarkers, alpha amylase and  cortisol are associated with several disease factors as diabetes, cardiovascular disease and other modern stress related disorders.

 

Although many research studies have been performed showing different proteins, enzymes in the body react to electromagnetic radiation, very few have pulled it all together at these very low exposure levels, for short periods of time, and using a noninvasive test medium – saliva. I believe the application of this study will allow us to test people or children in their own settings for EMF  reactivity to a host of wireless and EM signals.

 

It will help us convince public officials reactions to Electromagnetic signals are real not psychological. At the Cell Phone Senate hearing in Wash DC last year, Sen Harkin, chair of the hearing was very interested if a way was found to test for bio reactions to cell phones. One panelist commented that skin mast cells reacted to cell phone frequencies, Magda Havas has developed a way to show heart beat changes, and I believe this is one more in hopefully, an arsenal of ways that will be developed, noninvasively, to prove electromagnetic reactions to different  EM frequencies and electronic products are real

 

If you know of any doctor interested n electromagnetic sensitivity please pass the study on to them.

 

My summary of the Abstract and the Abstract follow. For a complete understanding of the parameters and results of the study please access the whole study.

My Summary

 

Fifty seven people were divided up into different scenarios of exposure conditions then exposed to 900 Mhz GSM frequency transmitter under 3 power density (PD) settings,  The PD setting were "high" 2126.8 microW/m2 (.2126 microW/cm2)- lower than Russian standards;  "medium" 153.6 microW/m2 (.0153 microwatts W/cm2.) –close proxity to WIFI transmitter signals;  and”low” 5.2 microW/m2 (.0005 microW/cm2) – This reading can be found in many rural/surburban readings w/o smart meters or wifi close by but still have good cell phone receptions.  Saliva samples were taken of 3 stress related bio markers ‘Cortisol, alpha amylase  (carbohydrate digester)  and IgA immunogloblins to test for reactions to the exposure settings. It was found the participants responded to all 3 exposure conditions in 2 of the biomarkers, Cortisol and alpha amylase, but not IgA. Authors conclude that “RF-EMF in considerably lower field densities than ICNIRP-guidelines may influence certain psychobiological stress markers

 

Abstract

OBJECTIVE: The present study aimed to test whether exposure to radiofrequency electromagnetic fields (RF-EMF) emitted by mobile phone base stations may have effects on salivary alpha-amylase, immunoglobulin A (IgA), and cortisol levels.
METHODS: Fifty seven participants were randomly allocated to one of three different experimental scenarios (22 participants to scenario 1, 26 to scenario 2, and 9 to scenario 3). Each participant went through five 50-minute exposure sessions. The main RF-EMF source was a GSM-900-MHz antenna located at the outer wall of the building. In scenarios 1 and 2, the first, third, and fifth sessions were "low" (median power flux density 5.2 muW/m(2)) exposure. The second session was "high" (2126.8 muW/m(2)), and the fourth session was "medium" (153.6 muW/m(2)) in scenario 1, and vice versa in scenario 2. Scenario 3 had four "low" exposure conditions, followed by a "high" exposure condition. Biomedical parameters were collected by saliva samples three times a session. Exposure levels were created by shielding curtains.
RESULTS: In scenario 3 from session 4 to session 5 (from "low" to "high" exposure), an increase of cortisol was detected, while in scenarios 1 and 2, a higher concentration of alpha-amylase related to the baseline was identified as compared to that in scenario 3. IgA concentration was not significantly related to the exposure.
CONCLUSIONS: RF-EMF in considerably lower field densities than ICNIRP-guidelines may influence certain psychobiological stress markers.
