Speech on X-Ray
Speech on why X-rays should be taken
Today our organization is going to talk look at some issues surrounding X-rays. Many people in our community for a long time have had misconception about x-rays. However, these misconception have not been true since various researches that have been done have proved otherwise.
There are many complications that we experience in our daily life in terms of our health. Some of them can only be identified and solved through X-ray because of their ability to pass through human tissues. Yes, all of us knows that too much X-rays radiation in large quantity can be harmful therefore all the necessary precautions have been always put in place to make sure that this does not happen, as echoed by David Attwood (1999).
rays are always part of the electromagnetic spectrum which also includes ultraviolet light, radio and infrared waves. Since they have a long wavelength as compared to light, they are able to pass human tissue. While the rays are used it is not possible to feel them, and they do not hurt in one way or the other. The modern X-rays machines that we current have are made in such a way that they use very small doses of X-rays and this is fairly safe for the patients.
The process of X-ray is not that involving that any of you should fear. The process is very simple because once the X-rays pass through the patient they are then collected on a sensor which was film in the old days, but now it is a computer imaging sensor. They have the capability of showing a 'shadowgram,' the denser bits' which are like the bones, showing up to be lighter as compared to less dense soft tissues, like the soft palate. According to Mettler FA.,( 2005), the reasons behind it is due to the fact that X-rays can pass through the tissues more easily as compared to when they pass through the hard tissues, hence more tend to be collected on the sensor. When looking at an X-ray film or screen is like you are looking at a black and white photographic negative where the tonal values have been reversed while the black bits are white and vice versa.
How safe are these X-rays?
Most diagnostic investigations have shown that there are no adverse effects from irradiation. Of course, as research by Goldstone K, (2008) indicates there are various types of radiation effect, however the ones that can occur in diagnostic practice are only a few and their likelihood is very minimal. For instance, in a simple X-ray examination like in chest X-ray or X-ray of the abdomen, skull, arms, pelvic region, knees or shoulder, the amount of radiation received is always very low and is equivalent to an amount less than a year of radiation exposure from natural sources. Even though at this level of exposure we cannot rule out carcinogenic and genetic effects that has still remained theoretical possibility since no practical evidence has ever shown such effects from any human studies.
For those who might be pregnant or suspect to be pregnant may tell their doctor prior to having the X-ray. However, that does not mean that the unborn baby will be at risk, no! It is just a precaution, but there is small risk of most diagnostic X-rays to an unborn baby. What we know is that any treatment must have its side effect, and also in X-ray, in some people, it is possible for injection of a contrast medium to cause side effects like: Nausea, a feeling of warmth or flushing, lightheadedness, a metallic taste in the mouth, hives, or itching.
Let us stop worrying much when we are told to undergo X-rays because those who will carry out the process are our health professionals called radiographers. They have been particularly trained on how to use imaging technology likes X-ray machines, ultrasound scanners, and computerized tomography (CT) scanner. The machine they use in that process is very simple and should not leave you in fear. The machines have major parts such as X-ray tube, lead shielding, and a photographic plate. This x-ray tube is like a giant bulb that uses high voltage electricity in generating X-rays. The role of the lead shielding is to direct the X- rays towards that section of your body to examined and prevents their escape to all…[continue]
