Specific Purpose: I am going to be informing my classmates about the development of X-rays and their use in the medical field.
Thesis: Almost everyone knows that X-rays exist and generally what they are used for, but I am going to explain more about their development, use, and risks involved.
I. Introduction
a. Almost everyone has had exposure to X-rays for one medical reason or another, but the medical field has come a long way since these important rays were discovered.
i. According to Early History of X-rays by Alexi Assmus, a German scientist named Wilhelm Conrad Roentgen in 1895 first discovered X-rays. ii. On December 22nd 1985, the first X-ray image was captured of the left hand of Roentgen’s …show more content…
In pregnant women this radiation, in any dose is especially harmful to their soon to be baby.
i. In a New York Times article commemorating the life of physicist Ernest Sternglass, it was stated that Sternglass first discovered that exposure to x-ray radiation in pregnant mothers harmed their developing fetus and caused higher rates of infant mortality and childhood leukemia. ii. It is possible to compare the amount of radiation you receive from one x-ray procedure and compare it to the amount of natural radiation absorbed in our surrounding environment.
d. There is an entire field of science that is still being pioneered through dealing solely with x-rays.
i. In astronomy x-rays are used to view black holes and their activity since no light is emitted and they are also used to locate other stars and galaxies. ii. In the field of biology x-rays are used to capture images of ultrafast moving molecular reactions that we were unable to observe before such as photosynthesis. iii. In addition to medical imaging, x-ray therapy is used to kill cancer cells by damaging the DNA of the cells using radiation, however this procedure can cause harm to other cells in the body and needs to be carefully planed …show more content…
Apart from their use in the medial field, x-rays are making it possible to view natural phoneme happen step by step.
c. Depending on the exposure time, x-rays do emit a certain amount of electromagnetic radiation, which should be monitored in healthy humans and entirely avoided by pregnant women.
d. Despite their risk, a typical x-ray of your broken arm only exposes one to a very small portion of this harmful radiation.
