Advantages And Disadvantages Of The Electromagnetic Spectrum

Light waves are a form of electromagnetic waves, which consist of patterns of electric and magnetic energy. The visible spectrum is only a small part of the electromagnetic spectrum-the

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

Gamma: this is a ray of electric radiations this is a part of electromagnetic spectrum. In the high energy and low wave frequency part. When ionising gamma rays pass through gamma because they are weak, travel through space and vacuum.

- 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.

1895 – X-rays were discovered accidentally by physicist Wilhelm Conrad Rontgen. Rontgen was working on a experiment and testing whether cathode rays could pass through glass. He noticed that a nearby tube emitted fluorescent glow of crystals. The air in the tube was released, high voltage applied, the same tube emitted a fluorescent glow. When Rontgen covered the tube in a heavy black paper, a green light could be seen. He concluded that a new light ray was being broadcast. Rontgen discovered that the light was very powerful and the same ray could pass through human tissue, but not through bones and metal objects. Medical applications were soon to follow.

Radiology Technologist have been around for almost a century. “Radiology Technologist works in various places taking diagnostic imaging examinations for patients, which are x-rays, magnetic resonance imaging, and mammography.” (eHow) This job is one of the few in the world that can give the risk of cancer to the rad-techs. And is stilled one of the most needed in the medical field. Radiology Technologist needs to understand computers and what the x-rays show, and how to set up a patient for and x-ray to be taken. Radiology Technologist are one of the highest paid in the medical field. This is because the job has more risk than any other job in the medical field. The radiology technologists have used x-rays for what has almost been in use

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 are electromagnetic waves of very short wavelength and high frequency, in the range 0.001nm to 10nm. Due to their high frequency (therefore meaning high energy), x-rays penetrate flesh and may cause ionization of atoms they encounter. The body tissue absorbs energy and the intensity of the beam is reduced when x-rays pass through the body. Denser material, such as bone, absorbs more X-radiation.

Also, x rays are capable of detecting many other issues such as cancerous masses or pneumonia as well as even dental problems all of which, again, can and have saved many lives [4]. For comparison, 400 million people are subject to x rays annually, which save substantially more lives than those of which were killed in japan [5]. Radiation can also be applied, not only to see but also to save patients in that it can be used, since it damages tissues, to kill things like tumors and other potential dangerous or life threatening masses within your body. Ironically enough it kills what it causes and for purpose of numbers, women with breast cancer had a survival rate of 25.1% in 1944 that more than tripled to 76.5% in the years 1995-2004 [6]. Also, now, 67% of women receive radiation treatment after having been diagnosed and the number is increasing [6]. But, beyond the medical field there are also economical advances that are largely caused by the use of nuclear power. These include the implementation of nuclear power plants that provide the cleanest and quickest way of generating electricity [7]. Also, to again throw numbers into the equation, fossil fuels are being consumed faster than they can be produced and the fuel for nuclear reactors, Uranium-235, is only worth 20%,

Electromagnetic radiation behaves both as particles (called photons) and as waves. Wavelength () and frequency () are related according to the equation

X-rays were discovered by accident in 1895 by the German physicist Wilhelm Conrad Roentgen. Roentgen was already an accomplished scientist with forty-eight published papers. He had a reputation among the scientific community as a dedicated scientist with precise experimental methods. Roentgen had been conducting experiments at the University of Wurzburg on the effect of cathode-rays on the luminescence of certain chemicals. Roentgen had placed a cathode-ray tube, which is a partially evacuated glass tube with metal electrodes at each end, in a black cardboard box in his darkened laboratory. He sent electricity through the cathodre-ray tube and noticed something strange his laboratory. He saw a flash of light

A focus on the equipment is most important as it relates to the human-machine interaction (we learnt about this in the HCI project in class, as well as in lab). That is to say, the need is not necessarily for more powerful x-rays but rather x-ray imaging that facilitates screeners’

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.

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
