I. Ordinary X-rays are used to diagnose many conditions and can be used to see a variety of things in the body,

Next, refraction was studied. This was accomplished by noting the placement of a prism, and then putting down place markers. Then, while one looked through the prism, additional place markers we put down that appeared to line up

You already know too much radiation is not a good thing, but it has been proven that no diagnostic x-ray test gives off the amount of radiation it takes to harm a fetus and cause any adverse effects. The

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

The aim of this study is to research the mechanisms and therapeutic effects of x-ray treatment on rats after spinal cord injury. Their hypothesis was that x-ray irradiation could alter the microcirculation of the injured site, impede the deterioration of the spinal cord, and advance the recovery of structure and function after spinal cord injury in rats.

In order to keep frequency of exams to minimum, which will lower a patients exposure to radiation I think it is best the follow guidelines set by a panel of dental professionals. There are a set of guidelines called “The Selection of Patients for X-Ray Examination” which was accepted by the American Dental Association (ADA) in 2002 , and these guidelines were updated in 2004 , being republished. These guidelines will aid me in taking the proper images , and frequency of exams. An example of how the guidelines will help me would be evaluating a new patient for oral manifestations of disease. I would first examine the patient visually utilizing a dental probe and if the proximal surfaces can’t be viewed clearly then I would be proceed

Since x-rays were discovered in 1895, there have been several improvements made to diagnostic x-ray to make it safer for both the patient and the radiographer. Some of these improvements include, aluminum filters, protective housing, lead shields/ aprons, and quicker exposure film. These changes have undoubtedly improved the diagnostic radiation process, however both patient and radiographer will still receive some dose of radiation. “The effects of radiation on tissue are divided into two types: deterministic and stochastic. A deterministic effect describes ionizing radiation-induced damage that occurs once a certain threshold is exceeded and increases in severity the greater the dose.1. (pg2-3) Some of the more extreme deterministic effects that occur with exposure to high amounts of radiation in a short period of time are: Skin Erythema/Necrosis, cataracts, sterility, radiation sickness, and death. Stochastic effects are probabilistic and there is no threshold amount that must be reached. As the amount of exposure increases so does probability of effects. However the amount of exposure does not correspond to the severity of the effects. Some of the stochastic risk can include development of various types of cancer and hereditary defects. It is more difficult to track the long-term stochastic effects that occur during chronic low-doses exposure because there are other additional factors that must be taken into account. “We are all exposed to background radiation. The

Since the technologies being used only bounce waves of the body surface, this leaves then skin highly exposed to concentrated amounts of radiation. Health side effect studies of full body scanners have been labeled classified and inaccessible to the general public. Four professors from the University of California- San Francisco, whom are well respected cancer, X-ray crystallographers and imaging experts stated in a letter to the Obama administration that, “The low-energy rays do a “Compton scatter” off tissue layers just under the skin, possibly exposing some vital areas and leaving the tissues at risk of mutation. When an X-ray Compton scatters, it doesn’t shift an electron to a higher energy level; instead, it hits the electron hard enough to dislodge it from its atom.” The authors note that this process is “likely breaking bonds,” which could cause mutations in cells and raise the risk of cancer (Johnston). Furthermore, the UCSF researchers write in their letter, “older passengers are more susceptible to mutagenic effects of X-rays, and “the risk of

Human body is so complicatedly designed that even a minor issue in an internal organ or organ system can lead to very major consequences for the patient to bear both physically as well as mentally. But with the increase in advancements in science and technology, medical science has reached to extremes for finding out the solutions to every problem faced in the treatment of health problems or any problem faced in the surgeries or operations. When surgeons faced the problems of not being able to see the inside picture of the various parts of the bodies then x-ray techniques were invented out of which chest X-ray is known to be the most important one. Actually a chest X-ray is known to be very fast and painless

Diagnostic radiology has evolved into being the foundation of medical institutions across the nation; yet, with more and more pediatric patients needing a radiographic image, there are greater risks of calamities. Shortly after the 20th century X-ray scare was resolved, hospitals nation-wide used the state-of-the-art machine to diagnose broken bones, teeth snags, infections, and even certain cancers. Along with new medical standards and safety measures, followers of Wilhelm Röntgen (the inventor of the X-ray) discovered the properties of X-radiation (Hart 48-50). Being close to gamma rays on the electromagnetic spectrum, X-radiation fully penetrates the human body, and since they are produced from a changing nucleus, they are able to affect and change the nucleus (cells) of the absorbing matter (Cancer 1-4; Burrill (2) 59-62). Oftentimes, the radiographer will not line up the machine correctly with the organ, tissue, or bone in question and, therefore, will tell the patient they must retake the image. One X-ray of the midsection is equal to three full days of background radiation (Hart 50). Radiologic technologists do not keep records of patients’ prior radiation exposure so it is up to them to discuss (with a general practitioner) and know their limits (Choy 88). A

In this article "Airport Screeners Could See X-rated X-ray's" Joe Sharkey tells us a little bit about a new airline security program. Sharkey advertizes that airlines are trying to bring in X-ray units that will be able to look beyond clothing, to the outline of bare skin. This precaution is becoming effective because technology is getting more advanced. Since metal detectors can’t be as reliable as we once thought, serious measures need to be demanded. However, scientists have discovered the previous precautions of metal detectors are irrelevant due to liquid hazard that they cannot detect. This article even says, “it found that federal airport screeners using metal-detecting magnetometers did a miserable job identifying weapons concealed

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
