Electromagnetic radiation
[attachment=50072]
Electromagnetic radiation or EMR is a form of
Energy emitted and absorbed by charged
particles, which exhibits wave-like behavior as
it travels through space.radiation is self sustaining
energy with electric and magnetic field
components.
TYPICAL HAZARDS
Electrical hazards
Fire hazards
Biological hazards
Effects cont…
Expanding use of cellular technology has led to some speculations that ‘electromagnetic pollution’ is causing significant risks to human health.
The amount of energy absorbed by the body is called the ‘Specific Absorption Rate’ expressed in (W/Kg).
Biological effects that result from heating of tissues by RF energy are referred to as “thermal” effects.
However studies indicate that biological effects may be caused without heating of tissues referred to as “non-thermal effect”
Increase in cancer risk
Mobile phone use >10 years doubles risk of brain cancer.
Risk is highest for ipsilateral (on the same side of the head where the instrument is held) exposure
Cell phone use also increases risk of glioma, acoustic
neuroma, salivary gland tumors uveal melanoma,
non-Hodgkin lymphoma, facial nerve tumors,
skin, blood, testicular and breast cancer
