APPLICATION OF RADIATION DURING AN X-RAY OPERATION IN A HEALTH CENTRE
INTRODUCTION
Radiation which is composed of x-rays is a form of electromagnetic radiation. X -rays have a wavelength in the range of 0.01 to 10 nanometers. This corresponds to frequencies in the range of 30 petahertz to 30 exerhertz and energies in the range of 120 ev to 10 kev. They are shorter in wavelength than UV rays and longer than gamma rays. The invention of this has been instrumental in the medical as will be discussed in the main body.
Definition of terms used in an X-ray operation
Radiation refers to a process in which energetic particles or waves travel through a medium or space. There are two types of radiations namely ionizing and non-ionizing. On the other hand emission is a term that refers to the process by which a higher energy quantum mechanical state of a particle becomes converted to a lower one through a photon, resulting in production of light. Finally X-rays are a form of electromagnetic radiation, which is just like visible light. (Allen, 1973).
X-RAY OPERATION IN A HEALTHY CENTRE
In a health care setting an x-ray machine sends individual x-ray particles known as photons during an X-ray operation. These particles pass through a body and a computer or some special film is used to record the images created during the exercise. For the structures which are dense such as bones will block most of the x-rays particles, and appear white. Metals and contrast media like special dye used to highlight areas of the body also appears white while those structures containing air will be black, and muscle ,fat and fluid appears as shades of gray (Saunders,2005)
The typical stationery radiographic x-ray machine also includes an ion chamber and grid. This ion chamber is basically a hollow plate located between the detection medium and the object being imaged. It determines the level of exposure by measuring the amount of X-rays that have passed through the electrically charged, gas-filled gap inside the plate. This allows for minimization of patient radiation exposure by both ensuring that the image is not underdeveloped to the point the exam needs to be repeated and ensuring that more radiation than needed is not applied (Rodgers, 2008).
The grid is usually located between the ion chambers and objects and consists of many aluminum slats stacked next to each other resembling a Polaroid lens. In this manner, the grid allows straight x-rays to pass through to the detection medium but absorbs reflected x-rays. This improves image quality by preventing scattered (non-diagnostic) x-rays from reaching the detection medium, but using a grid creates higher exam radiation doses (Eastman, 2007).
Operation of the test
The X-ray operation test is performed in a health centre radiology department or in a health care provider`s office by an x-ray ...
