Electromagnetism Spectrum. Electromagnetic radiation

As a wave, EMR can characteristically be absorbed or emitted by charged particles. They also have the magnetic field, as well as electric component that oscillates perpendicularly and in fixed relationship with each other and perpendicular to the direction of the wave energy propagation. Electromagnetic waves are characterized by wavelength and frequency of their waves. In order of decreasing wavelength and increasing frequency, electromagnetic spectrum consists if the radio waves, the microwaves, the infrared radiation (IR) the visible light (UV), the ultraviolet radiation, the X-rays and finally the Gamma rays. In this spectrum, higher frequency and lower wavelength corresponds to proportionately more energy possessed by each photon. For example in this case, gamma rays photon has more energy compared to a Visible light photon. The characteristics of electromagnetic waves are shown in diagram 1 and 2. Diagram 1: Properties of the EM spectrum across each range. Diagram 2: Electromagnetic spectrum. EMR is often associated with electromagnetic fields, which propagates themselves freely without the influence of moving charges responsible for producing them because they operate at a distance from the charges that produced them (Condon, & Ransom, 2003). This way, EMR is also referred to as far field. In this context, near field EMR refers to those electromagnetic fields near the current and charges, which directly produced them. The static electricity and magnets phenomena are the best examples of near field EM. In electromagnetic radiation, the electric and magnetic fields are often induced by the changes in electric fields. This makes it to propagate itself as a wave. Such as relationship ensures both the electric and magnetic types of the fields stand in a fixed ration of their intensity to each other and in phase with nodes and maxima found at similar places in space. Electromagnetic radiations carries energy called radiant energy through space and continuously away from its source. They also carries both angular momentum and momentum, all of which are impacted matter upon which EMR interact with. Electromagnetic waves are often produced from other forms of energy when they are created, and they are converted to other forms of energy whenever they get destroyed. The photon is the basic unit and constituent of all form of electromagnetic radiation, and is the quantum of the EMR interaction. In classical physics, electromagnetic radiation is considered produced whenever forces act on charged particles to accelerate them. Fast moving electrons are sharply accelerated whenever they meet any region of force. Electrons are therefore, responsible for the production of most high frequency EMRs such as X-rays. This is because of their associated low mass. Quantum process also produces EMR. This happens when an atomic nuclei is made to under a process such as neutral pion decay or gamma decay. The effects of electromagnetic radiations on biological systems depends on the radiation’s frequency and power. Health effects of Electromagnetic waves In the 21st century, exposure to manmade EMR fields has been increasing steadily with increasing growing energy demand. Changes in social behavior, as well as the ever-advancing technologies have created more artificial sources of EMR. We are exposed to mix of weak magnetic and electric fields both at work and at home from the domestic appliances, industrial equipment, generation and transmission of electrical energy, and in broadcasting and telecommunication. There exists tiny electrical currents within human bodies because of chemical reactions, which occur as part of bodily functions, even where external electric fields are ...Show more

The risks associated with ionizing radiation in medical imaging practice, and the precaution required to protect against them
The ions that are produced as a result of these radiations are capable of bringing about biological changes (Holmes, White and Gaffney, 2011). It is an established fact that the longer wave length, lower frequency waves have less energy and is used for heating and radio.

The risks associated with ionising radiation in medical imaging practice, and the precautions required to protect aginst them
Doubling every 2-4 years, right after the 1960 the interventional procedures using radiation has substantially increased (Takeyama 1997). The medical imaging technology includes the following subjects under its heading:- 1) Radiography 2) Magnetic resonance imaging 3) Nuclear medicine 4) Photo acoustic imaging 5) Breast thermography 6) Tomography 7) Ultrasound The new techniques and procedures in the medical imaging are posing high radiation doses to the patients as well as the staff (Wilde et al 2001).

Electromagnetic induction

This research will begin with the statement that in electromagnetic induction, a current carrying wire induced a magnetic field around the wire. Cutting the field using a magnet will result to an induced emf, which is proportional to the rate of change of the magnetic field or speed at which the field is cut.
