Health Hazards

Extended exposure to electromagnetic fields (electropollution) is proposed to cause health risks by some medical professionals

cancerbirth defectsdepression learning disabilitiesChronic Fatigue SyndromeAlzheimer's diseaseSudden Infant Death Syndrome

Sources of Electropollution

• power lines and transformers• household wiring• microwave ovens• computers• televisions• clock radios• cellular phones• electric blankets• other electrical appliances
