National Toxicology Program study results finding exposure to wireless radiation significantly increased the prevalence of highly malignant heart and brain cancers in rodents, the American Academy of Pediatrics AAP has issued specific recommendations to reduce wireless cell phone exposure and updated their online resources for parents concerning cell phones and all wireless devices. Based on this new information, regulatory agencies need to make strong recommendations for consumers to take precautionary measures and avoid close contact with their cell phones, and especially limit or avoid use of cell phones by children reliable online pharmacy business online pharmacy 24 hour pharmacy rochester ny ed pills online. What Parents Need to Know. Please remember land-lines and hard-wired computers should be the first choice for children and teens Use text messaging when possible, and use cell phones in speaker mode or with the use of hands-free kits.
March 12, NASA Electromagnetic EM radiation is a form of energy that is all around us and takes many forms, such as radio waves, microwaves, X-rays and gamma rays. Sunlight is also a form of EM energy, but visible light is only a small Electromagnetic radiation of the EM spectrum, which contains a broad range of electromagnetic wavelengths.
Electromagnetic theory Electricity and magnetism were once thought to be separate forces. However, inScottish physicist James Clerk Maxwell developed a unified theory of electromagnetism.
The study of electromagnetism deals with how electrically charged particles interact with each other and with magnetic fields. There are four main electromagnetic interactions: The force Electromagnetic radiation attraction or repulsion between electric charges is inversely proportional to the square of the distance between them.
Magnetic poles come in pairs that attract and repel each other, much as electric charges do. An electric current in a wire produces a magnetic field whose direction depends on the direction of the current.
A moving electric field produces a magnetic field, and vice versa. Maxwell also developed a set of formulas, called Maxwell's equations, to describe these phenomena.
Waves and fields EM radiation is created when an atomic particle, such as an electron, is accelerated by an electric field, causing it to move. The movement produces oscillating electric and magnetic fields, which travel at right angles to each other in a bundle of light energy called a photon.
Photons travel in harmonic waves at the fastest speed possible in the universe: The waves have certain characteristics, given as frequency, wavelength or energy.
Electromagnetic waves are formed when an electric field shown in red arrows couples with a magnetic field shown in blue arrows. Magnetic and electric fields of an electromagnetic wave are perpendicular to each other and to the direction of the wave.
A wavelength is the distance between two consecutive peaks of a wave. This distance is given in meters m or fractions thereof. Frequency is the number of waves that form in a given length of time.
It is usually measured as the number of wave cycles per second, or hertz Hz.Electromagnetic radiation can be classified into two types: ionizing radiation and non-ionizing radiation, based on the capability of a single photon with more than .
Should that object possess an asymmetrical electric charge (where one side has slightly more charge than the other), its spin could emit electromagnetic radiation in the form of microwaves. — Shannon Hall, Scientific American, "Glittering Diamond Dust in Space Might Solve a Year-Old Mystery.

The photon is the quantum (the smallest possible unit) of electromagnetic radiation. In quantum mechanics, all phenomena in which charged particles interact with one another, as in the binding of protons and electrons in an atom or the formation of.
Electromagnetic (EM) radiation is a form of energy that is all around us and takes many forms, such as radio waves, microwaves, X-rays and gamma rays.
Sunlight is also a form of EM energy, but. The dangers of electromagnetic radiation are a major factor in many diseases and health problems such as fibromyalgia, headaches, lyme disease, ADHD and cancer.
But EMF affects ALL diseases.
