X-Ray
Since its accidental discovery in 1896, the x-ray has been an important tool in many different aspects. X-rays are electromagnetic radiation ranging in wavelength from about 100 A to 0.01 A. The shorter the wavelength of the x-ray, the greater its energy and its penetrating power. Longer wavelengths, near the ultraviolet-ray band of the electromagnetic spectrum, are known as soft x -rays. The shorter wavelengths, closer to and overlapping the gamma ray range, are called hard x-rays. The principal uses of x-rays are in the field of scientific research, industry, and medicine. Recently, there have been many new discoveries and advances in the use of x-rays in fields ranging from health to astronomy.X-rays are an important tool in health diagnosis and treatment. Within a few years of their discovery, x-rays were being used to locate foreign bodies, such as bullets, within the human body. High intensity x-rays, capable of destroying tissue, are used in the treatment of tumors. Rapidly dividing cancerous cells are especially vulnerable to x-rays. With the development of improved x-ray techniques, radiographs revealed the smallest differences in tissues, which resulted in the diagnosis of many pathological disorders. Recently, rese
X-rays have such a wide variety of applications and new uses are coming to light each day. X-rays are the wave of the future, from changing protein structures to observing black holes and galaxies light years away. The only limits of the possibilities are the limits of the human imagination needed to apply them. The discovery of x-rays was accidental; the discovery of using x-rays to cure all cancers may be as well. X-rays have the potential to continue making an impact on society for years to come. Although x-rays are very helpful in medicinal purposes, there are also some possible dangers. The routine use of X-ray diagnosis has in fact been discouraged in past years-by the American College of Radiology in 1982, for example-as of questionable usefulness. There have been numerous studies recently looking for a relationship between extensive x-ray radiation and increased cancer and heart disease possibilities. There is still no solid evidence to prove this, although researchers will continue to make sure this is not a large threat to the population. Another use of x-rays is diffraction, a method of determining atomic and molecular structures by measuring patterns of scattered X-rays after
