| dc.description | Roentgen’s discovery of X-rays resulted in the eventual invention of X-ray machines used to image structures in the human body and to treat health conditions. Adverse health effects of high levels of ionizing radiation exposure became apparent shortly after these initial discoveries. High doses to radiation workers would redden the skin (erythema), and this rough measure of radiation exposure was called the “skin erythema dose.” The use of very large doses, primitive dosimetry (dose measurement) such as the skin erythema dose, and the fact that many of these early machines were not well shielded led to high radiation exposures both to the patients and to the persons administering the treatments. The development of chronic, slow-healing skin lesions on the hands of early radiologists and their assistants resulted in the loss of extremities in some cases. These incidents were some of the first indications that radiation delivered at high doses could have serious health consequences. Subsequent studies in recent years have shown that early radiologists had a higher mortality rate than other health workers | |
| dc.description.abstract | The x-rays made possible when the physicist Wilhelm Roentgen discovered x-rays On Friday evening, 8 November 1895, Wilhelm Conrad Roentgen was investigating an electrical discharge generated in a paper-wrapped glass tube from which most of the air had been evacuated. The free electrons generated in the “vacuum tube had themselves produced another form of radiation. Roentgen noted that when the electrons were being generated, a fluorescent screen on a nearby table began to glow. Roentgen theorized that invisible emissions from the cathode-ray tube were causing the fluorescent screen to glow, Roentgen assigned the letter "X" ( "X" is the mathematical symbol for the unknown ) to represent the unknown nature of the ray and thus the term x-ray was born[1,2]. Roentgen started placing different objects between the tube and the fluorescent plate and was able to study several characteristics of X-rays. He was able to publish and reproduce his work and was awarded in 1901 the first Nobel Prize in physics. Roentgen recognized the value of his discovery to medicine and was able to produce and publish the first medical X-ray image, the image of his wife's hand (Figure 1.1) in 1896 [ | |
