What is the biggest difference between electromagnetic radiation and charged particles?
X-ray and gamma-ray generated by the electromagnetic energy, different from the RF transmitter generated by the electromagnetic energy. RF device electromagnetic energy belongs to the spectrum of the lower frequency of that end, can not break the molecules together with the chemical bond, it is classified as "non-ionizing" radiation. Where will there be electromagnetic radiation? There are many sources of electromagnetic radiation. Both inside and outside the human body are covered by natural and artificial radiation emitted by the energy and magnetic energy; lightning is one of the examples of natural radiation sources. As for the artificial radiation source, including microwave ovens, radios, television broadcast transmitters and satellite communications devices. Electromagnetic radiation in two levels, the frequency band radiation, radio frequency electromagnetic waves. Frequency of the national standard electric field strength of 4000v / m, magnetic induction intensity of 0.1mT; radio frequency electromagnetic wave unit is μW / ㎝ 2, the national standard limit of 40, for the general public environmental assessment value of 20%. Common law Coulomb's law: F = kQq / (r ^ 2); electric field strength: E = F / q point electric field strength: E = kQ / (r ^ 2);
Electromagnetic radiation is electromagnetic radiation, itself is not charged. When the wavelength is longer, the particle is not obvious, will not produce a significant force on the atomic level of objects; charged particles are charged particles, can be produced with the atomic level of the object, and even the role of the nucleus
