Abstract |
: |
An international and wide dispute is currently undergoing
about the radiation emitted from the electric current of high
voltage, domestic connections or appliances; and about their effects
on human beings either directly or indirectly. People are divided
about their risks between an exaggerating group and a group
that paid no attention to them. Researchers also show a discrepancy,
according to their results
As a result, legislation committees and organizations varied in
defining the exposure limits of electric and magnetic fields of 50/
60 Hz. This research puts forward an introduction to the extent of
this dispute compared to other types of radiation of electromagnetic
spectrum. It also clarified the variation of other research works,
exposure limits and causes. This study comes out with the followings:
First: Exposure to electric and magnetic fields within the permissible
limits issued by international committees, such as (ICNIRP)
and others. There has been no definite evidence that exposure
to these fields is linked to diseases such as cancer in children
or adults. In one hand, the scientific and statistic researches that
presented this link were short of controlling factors that interfere
in the occurrence of these diseases, or they were not supported by
researches confirming this link. On the other hand, there are many
researches that disapprove such link between those fields and cancer.
The main verification that can be used by those who approve
such link is the classification of the very low frequency electromagnetic
radiation as a carcinogen issued by IARC. Second: specialized
organizations open the door for researches in this field because
the idea of a link between exposure to electric field and
cancer still exists. Third: Technical faults, which increase radiation
pollution, should be avoided by putting rules for the methods
w «d « t?K «b bL ?¥
of electrical connections. Forth: Exposure rates below limits of the
electromagnetic emissions, due to high power and other electric
network, should be further reduced if possible economically since
there is no confirmed link between such rate limits and health.
However, technical faults are not accepted, i.e., they should be
fixed even exposure rates are very low. |
