Electromagnetic Spectrum Essay

Magnetic Resonance Imaging (MRI) in the 1970s to 1980s to present day. Has served as a medical imaging technique used in radiology to form detailed pictures of the body for both health and disease. In the MRI scanners, there are strong magnetic fields, radio waves, and field gradients in order to generate images of the inside of the body and appear on a screen. MRI and X-rays are not the same. MRI scans take more time, are louder, and usually require that the body goes into a narrow tube. While X-ray scans take less time, aren’t really loud, and don’t involve a narrow

The sound waves are produced by a random oscillating crystal, and are inaudible to humans. A instrument called a

Furthermore, X-ray of higher energy than required for imaging is used for radiation therapy. The radiation therapy makes use of ionization radiation (and no images) for the treatment of diseases, such as

- Even though the X-ray expose patient to harmful radiation it is used to see inside the human body and diagnose broken bones, gallstones and later tuberculosis.

1. Ordinary X-Rays can show a wide variety of things such as bones, teeth, bone fractures, and other abnormalities of bones and other things in the body.

We benefit greatly the benefits of long distance communication, eating food from different parts of the countries without fear of spoilage, radiation treatment, and heating up food in a matter of minutes, and a myriad of other wonders all do the wonders of waves, be they sound waves as well as light waves. In this timeline, we will look at all of the different light waves, their history, and their benefits.

Eye protection; such as spectacle/goggles to prevent dust or any other harmful substances from your eyes.

Infrared (IR) light cannot be detected by the human eye. It has an energy factor that is two or three less than visible light and so the retina cannot be triggered to see it. So, when applied properly, infrared light can be used to help the human eye see things that were not fathomable beforehand. Infrared light doesn’t give off much energy and therefore is not very hot. When objects aren’t hot enough to give off visible light, it gives most of its energy in the Infrared Spectrum and is used in science, art and more. Chances are that people use something that is involved with Infrared technology every day, but they do not even realize it! Infrared technology is used in simple household commodities like remote controls

X-rays are used to guide tubes or cameras through the body. It is used to look at the heart, lungs, and chest walls. They can also be used to rule out any other conditions that might be causing the weaknesses.

X-rays have numerous different effects on the tissues of the body, depending on the time of exposure and energy of the X-ray photons. Best contrast between different tissues is when the photon energy is about 30 keV, for diagnostic purposes. Resulting in the photoelectric effect dominating at this energy. The tissues absorb X-rays and electrons are released. The X-ray absorption depends on the number of protons in the nuclei of the atoms encountered. A high number will attenuate the beam, producing a strong x-ray shadow, enabling for a high quality image of

X-rays may be invisible waves found on the electromagnetic spectrum which can almost make their known danger seem of little importance because our five senses cannot measure their activity, however x-rays must not be taken lightly. Radiologic Technologist must keep in mind the dangers and gravity of the force that they are working with on a daily basis. Patients should have the right to their own safety when undergoing a medical procedure that requires the use of x-rays. Radiologic Technologist are the ones responsible for upholding this safety. They can and must do this in variety of ways that include, making sure the patient is knowledgeable about the procedure, using correct collimation to the part under examination, and by shielding the

→ An X-ray is an imaging test that uses small amounts of radiation to produce pictures of the organs, tissues, and bones of the body. When focused on the chest, it helps to spot abnormalities or diseases in the lungs.

There are many advantages of x-rays in dental radiation. We can use the x-rays to detect and confirm any diseases or lesions that may be in the mouth. They detect any trauma that may have happened to the teeth and or gums. We use x-rays to look and study the growth and development of teeth and gums in children and adults. With the advancement of the x-ray we can also detect any tumors, teeth that are missing or are coming in at an abnormal direction as well as educating the patients about their mouth and teeth.

radiation (the kind used in X-rays) is known to cause cancer at high doses, the risks of

With this stability and mass production, x-rays machines became very common everywhere. From large factories, to doctors offices, all the way to the corner store of small towns, where children and adults alike could insert a coin into a machine and view the bones in their feet. (3.) Because of their relative adolescences in the world, not much was known about x-rays or their effects on the human body. The first theories about the rays’ effects on the human body were that they had beneficial applications. With this being the only theory about their effect, widespread use went on, unmonitored, and unregulated. This unregulated use led to injuries but because of their slow onset the injuries were never attributed to x-rays. While some scientists tied certain skin burns to over exposure of x-rays it wasn’t until popular minds of the world like Thomas Edison, Nikola Tesla and William J. Morton expressed that they experienced eye pain when dealing with the rays for extended periods of time that people began to connect the dots and understand the negative
