The X-rays are, as the name suggests are a beam of rays. However, they comprise of very highly energetic radiowaves. The range of their wavelength lies between 10 to 0.01 nanometers, and they have frequencies in the range of 30PHz to 30EHz. They can be used in the analytical techniques as the crystallography and in medical analysis of the diseases. They were discovered by professor Roentgen in the year 1985.
One of the well-known facts about X-rays is that, they are artificially produced when; an electronic beam strikes a metal in their path. This happens in the cathode ray tube. However, in the nature the various sources undergoing nuclear activities also emit X-rays. The useful facts about X-rays are that they are very highly energetic and therefore, they can pass through the air and other things having lesser density. Similarly, they can pass through the thin plates of denser substances as well. However, their passivity reduces as the density increases. Therefore, when they are passed through the body, they produce a pattern according to the densities of the contents of that region. This property among the various facts about X-rays is used in the medical field.
Like the visible light, they can also affect the photographic plate. Therefore when these emergent X-rays are focused on them a photograph of this pattern developed.
They are highly energetic and therefore they can be harmful to the body. For this reason, during the medical analysis, a unit named rem is used for recommending the dose for a particular patient. Its bigger unit is the sievert i.e. the Sv. 1 Sv is equivalent to100 rem. However, both of them are too large units for their use medical field. Therefore, a smaller unit, the millimrem is generally used. The doses of the X-rays vary from case to case. They are in some cases, as high as 900 mrems.
The facts about X-rays also includes that, they are not detectable to our vision system. However, as they are highly energetic and therefore they are harmful to the eyes and therefore this should be prevented in case.
They are widely used in the medical diagnosing of the different problems in the body. The use of the X-rays for diagnoses comes under the field of radiography. They are commonly used in the detection of the fractures in the bones, or cartilages, or the presence of some foreign body. They also can show the abnormalities in the softer tissues as well. These abnormalities can be cancers, tumors, ulcers, swollen tissues, etc.
The X-rays have a very wide use in the other fields as the science, research and the industry. They are used in the study of properties of the structure of crystals of compounds. In addition to this, they are also used for many more types of analyses.
