|Chromosomal damage in human diploid fibroblasts by intermittent exposure to extremely low-frequency electromagnetic fields|
|Austria||Created: 7 Sep 2005|
Chromosomal damage in human diploid fibroblasts by intermittent exposure to extremely low-frequency electromagnetic fields.
Environmental exposure to extremely low-frequency electromagnetic fields (ELF-EMFs) has been implicated in the development of cancer in humans.
An important basis for assessing a potential cancer risk due to ELF-EMF exposure is knowledge of biological effects on human cells at the chromosomal level. Therefore, we investigated in the present study the effect of intermittent ELF electromagnetic fields (50Hz, sinusoidal, 5'field-on/10'field-off, 2-24h, 1mT) on the induction of micronuclei (MN) and chromosomal aberrations in cultured human fibroblasts. ELF-EMF radiation resulted in a time-dependent increase of micronuclei, which became significant after 10h of intermittent exposure at a flux density of 1mT.
After approximately 15h a constant level of micronuclei of about three times the basal level was reached. In addition, chromosomal aberrations were increased
up to 10-fold above basal levels. Our data strongly indicate a clastogenic potential of intermittent low-frequency electromagnetic fields, which may lead to considerable chromosomal damage in dividing cells.
( WHO bases its decision on the science)Previous earlier animal experiments already showed a dose-dependant genotoxic effect under high frequency radiation. Further, in the brains of rats increased functionless nerve cells were found after two hours of mobile phone radiation. Two corroborative epidemiological studies showed a three- to four-fold increased risk for auditory nerve cancers after ten years of mobile phone use.
Dear Mr Repacholi:
You claim that WHO bases its decisions on SCIENCE.
If that is trully the case then I would suggest that you start to look at the scientific studies that are available.
I don't mean,just the wireless industry funded studies. If you are not concerned about the preservation of adult health ,then for Gods sak ,
at least,protect our childrens health.
Vienna Doctor’s Chamber (Wiener Ärztekammer) warns of excessive mobile phone use by children.
Data for the cancer risk from mobile phone radiation are increasing new catalogue of guidelines advises cautious contact with mobile phones.
Wien (OTS) - The Vienna Doctor’s Chamber (Wiener Ärztekammer) warns expressly against excessive mobile phone use especially by children.
The reason for this is the recently presented “Reflex Study” (Reflex-Studie) in which a definite genotoxic effect of mobile phone radiation was proven.
The first consequence is that the Doctor’s Chamber (Ärztekammer) has now drawn up a catalogue of guidelines, which stipulates specific rules of behaviour
for use of mobile phones.
The Reflex Studie (Reflex Study), which was supported by the EU at a cost of more than two million Euros, was carried out at various important research
centres in Europe including the Wiener AKH. In the course of this study, the so-called mutagenicity of a substance, in this case in by electromagnetic field,
was tested. They looked for changes in the genes which are the possible beginning of a cancer disease. One part of the study tests was carried out on
human promyelocytes a preliminary stage of the cells of blood formation. A mutation of such cells can as a further consequence lead to leukaemia and
similar illnesses of the blood forming system.
The results from these studies can be summarised in one sentence: There is indeed a genotoxic effect on human cell cultures from mobile phone radiation
at a strength that is supplied by every GSM mobile phone.
First studies confirmed
Previous earlier animal experiments already showed a dose-dependant genotoxic effect under high frequency radiation.
Further, in the brains of rats increased functionless nerve cells were found after two hours of mobile phone radiation.
Two corroborative epidemiological studies showed a three- to four-fold increased risk for auditory nerve cancers after ten years of mobile phone use.
With the now presented “Reflex Study” (Reflex Studie) a cell-biological relationship has been proven for all these results.
Eric Huber, Speaker for Environmental Medicine for the Doctor’s Chamber for Vienna (Referent für Umweltmedizin der Ärztekammer für Wien):
“If medications delivered the same test results as mobile phone radiation one would have to immediately remove them from the market”.
The Vienna Doctor’s Chamber (Wiener Ärztekammer) finds it necessary to call upon the population to take more care with use of mobile phone equipment, especially children. Huber: “We must assume that children are more sensitive towards high frequency radiation than adults since the skull bones are thinner
and the children’s child-like cells show an increased rate of division, in which they are more sensitive to genotoxic effects”.
That is why they have decided to follow the example of the British Ministry of Health and the Danish Health Council, and to also warn against excessive
mobile phone use, especially by children, in Austria.
The following guidelines for mobile phones should according to Huber, “Expressly not only be valid for children”.
> Children under 16 years should not use mobile phones.
> Only use mobile phones in emergencies and then only telephone briefly.
> A mobile phone in the trouser pocket and also the sending of SMS messages under the school desk can influence fertility and should be completely avoided.
> If sending SMS messages keep the mobile phone away from the body.
> Turn off the mobile phone at night if left turned on, do not keep it near the head.
> Also, headsets are not recommended, since the cable frequently transmits the signal like an antenna.
> Play no games on the mobile phone.
> Keep the mobile phone away from the head during the telephone connection.
> Keep a couple of metres distance away from other people, they are being radiated with you.
> Less mobile phone telephone calls mean less radiation from mobile phone
> Internet via cable connections UMTS and WLAN lead to high radiation exposure.
----- Original Message ----- From Dr Repacholi
Robert WHO bases its decision on the science...if the science does not support your position this is not my problem.
It is a cheap shot to say that because the WHO position is the same an an industry position that we are in bed with industry...t
his is patently untrue and it does you no good to even suggest it..
Our Director General claimed to be hypersensitive...this does not mean that we should base our decisions on anything but the valideated evidence..
Pity is that people such as yourself wont listen to the science...it is one of our greatest resources...all successful countries reply on it.
