Radiation Vs Man Made Radiation

1. In 1895 the discovery of X-rays by the German scientist of physics, Wilhelm Roentgen, created an amazing step forward in the history of medicine. For the first time ever, the inner workings of the body could be made visible without having to operate.

Radiation is one of the main forms of energy (Pettigrew 1). In today’s environment we are only familiar with the basic types of radiation. These types are in the form of

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. ("History of radiography," )

Ultraviolet (UV) radiation is present in normal sunlight and sunlamps. “The sun emits energy over a broad spectrum of wavelengths: visible light that [one] can see, infrared radiation that [one] feels as heat, and ultraviolet (UV) radiation that [one] cannot see or feel. UV radiation has a shorter wavelength and higher energy than visible light. It affects human health both positively and negatively” (U.S. EPA). There are multiple types of ultraviolet radiation known to scientists and each affects human in different ways. “The longer ultraviolet rays (UVA), which penetrate deep into the skin, are responsible for tanning. Shorter rays (UVB) damage superficial skin cell layers, causing sunburn” (Harvard). Medical researchers at the Skin Cancer Foundation found that “the cumulative damage caused by UV radiation can lead to premature skin aging (wrinkles, lax skin, brown spots, and more), as well as skin cancer” (Skin Cancer Foundation).

A scientist would need a glass tube with positive and negative electrodes. The tubes were called cathode tubes, and they were common in the late 1890s. The air leaves the glass tube, and a florescent glow is produced when a high voltage runs through the tube. The scientist needs to cover the glowing tube with a heavy, black paper or cardboard. Then the scientist will see the green colored fluorescent light illuminating from the box. This is known as the X-Rays which energizes the phosphorescent materials in the room. The newly discovered ray would pass through objects, and it can cast a shadow of most solid objects. The ray consists of electron passing through the matter underneath the cathode tube. It can pass through human tissues, but it cannot pass through bones and metal

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

Everyday, at one point or time, we see the Sun. “The Sun is the brightest object in the sky, and without it, we would not be alive. The Sun gives off light and heat, and we need both to make the Earth a warm, comfortable place to live”(Hudson). All the time, rays and particles have light are entering the Earth’s atmosphere and bouncing off of and hitting objects all around us. Even though we need the Sun’s light and heat, too much of it is bad for our body. Severe light absorption can lead to skin cancer.

It was on November 8, 1895, that German physicist, Wilhelm Roentgen, accidently discovered the first x-ray when experimenting with his machine on his wife’s hand (Evolution

Professor Roentgen discovered X-Rays on November 8, 1895. He discovered them when he was working with a cathode ray tube in his laboratory and noticed that their was a new ray that would pass through most substances, they would cast shadows on a piece of film. They were named X-Rays because in mathematics "X" is used to indicated the unknown quantity. At the time the news on Roentgen's discovery had spread throughout the world and had an instant impact on the medical field. The impact of the X-Ray hasn't changed and, it is still heavily relied upon in today's society. These were some of the major medical advancements discovered in the 19th century, however there was more advancements to come in the 20th

According to the health physics society, radiation is an energy that comes from a source and travels through space which may be able to penetrate various materials. In the past few weeks of our chemistry class I have learned that atoms whom have an unstable nuclei are radioactive, these atoms give off excess energy which are radiation rays. Radiation varies from gamma, beta, and alpha rays. Gamma rays have the shortest wavelengths and highest frequencies. Gamma rays are the most energetic form of light produced by the hottest regions of the universe and emitted by the nucleus of radioactive atoms. Because of this, gamma rays are used to penetrate tissue property, such as in the use of CT scans, and radiation therapy. Alpha particles are also ejected by the nuclei of unstable atoms; however, they are large and consist of two protons and two neutrons. Although alpha particles have a high mass, they are the most destructive form of radiation with a low penetrating force; a single piece of paper can block alpha particles. Beta particles are much

They can play crucial part in determining what can be wrong with a patient. The first X-ray was discovered in 1985 by Wilhelm Roentgen, a German scientist (Cite-radiology history). X-rays are described as “electromagnetic energy waves that act similarly to light rays, but at wavelengths approximately 1,000 times shorter than those of list” (German scientist discovers x-rays). The first X-ray was in use during the Balkan war. During this time in 1897, they used the X-ray to determine if there were any bullets in the soldiers, or to find if they had any broken bones. Although the X-ray was found very helpful, scientist later started to discover the effects that the radiation could have on the patient. The event that caused the entire scientist community to raise concern. They realized that the effects of X-ray could cause patients to end up with burns and possibly cancer. After several reports of burns and the death of Clarence Dally (due to cancer form working with X-ray), these events raised concern for many. Scientist and doctors became aware of the risk X-rays imposes, and started to take precautions to protect them and the patients. Thanks to this discovery, many patients and x-ray technicians now are required to wear lead aprons. These aprons help protect against the radiation x-rays give off. The technician also have to wear a dosimeter. A dosimeter measures the amount of radiation the technician receives while

Ultraviolet light (UV) Introduction The ultraviolet light is found around our lives, even if we do not concern about it too much. It is a kind of electromagnetic radiation that comes from the sun and people can not notice it with their eyes. The UV light only embodies 10% in the sun, and merely a little part reach on the ground. The UV light has the shorter wavelengths than the others. In addition, it also benefits our lives. We use the UV light on the periodontics, cleaning, the discovering of the real money, or dry out our nail. On the other hands, the UV light also has some negative impacts in our human bodies, the UV light mainly absorbed in the superficial, which means the dead layer of the epidermis.It can cause corneal burns, sunburn, seriously cause the skin cancer. Although it

The X-Ray was invented in 1895 by Wilhelm Conrad Roentgen. It all started with a vacuum tube called a Crookes tube, with this Roentgen noticed that by pressing a button that activated an electric current through it a shadow was projected onto a screen that showed the photograph of his wife’s hand with a ring

One of the first radiology departments was created at the Glasgow Royal Infirmary in 1896. Dr. John Macintyre, head of radiology at Glasgow, created the first x-ray of a kidney stone, an image showing a penny in the throat of a child, as well as an image of a frog’s legs in motion. An American physiologist experimented with x-rays in order to trace food as it traveled through the digestive system (Waters, 2011). In 1896, Dr. Hall-Edwards became one of the first physicians to use x-rays to diagnose a patient, when an x-ray revealed that a needle was embedded in the patient’s hand. X-rays quickly became a vital tool used by doctors, to diagnose patients (Roentgen’s discovery of the X-Rays, 2006). In 1897, x-rays were first used to locate bullets

X-rays are used for medical purposes. They are a form of radiation named electromagnetic waves (EM Radiation). They are used to take pictures of the insides of the human body which come out in black and white. The X-ray was first developed in 1895 by a man named Wilhelm Conrad Roentgen. While He was working with a cathode-ray tube in his laboratory, Roentgen observed a fluorescent glow of crystals on a nearby table close to his tubes. The tube that he was working with consisted of a bulb with positive and negative electrodes enclosed within it, when the air inside of the tube left and when a high voltage was applied to it , the tube produced a fluorescent glow. Roentgen then shielded the tube with heavy
