In November 1985, a German physicist named Wilhelm Roentgen was experimenting with a Crookes tube in his laboratory. The Crookes tube was developed by the English physicist William Crookes. A Crookes tube is a gasless glass container that contains a negatively charged cathode and a positively charged anode with an induction coil to carry a current. Roentgen discovered that when a high voltage was applied to the tube, it emitted an invisible source of rays that caused a fluorescent screen to glow. This fluorescent screen was approximately 9 feet across the room. This was an unexpected discovery because at the time the glass tube was shielded by heavy black cardboard to contain the glare of electrons reacting inside the tube. After this happened, Roentgen tried using other sources including, but not limited to, paper and books from his desk to try to interrupt the path of the invisible ray, to no avail. (UCSD.Edu) Roentgen decided to further his experiment with the new information he found by using a photographic plate as a medium and noticed that a fog appeared after exposure to invisible rays. He soon encouraged his wife to allow him to use her hand in his tests and the first x-ray of a human body part was produced. (UCSD.Edu) Soon after experimenting with and producing his first x-ray, he had written and presented his findings to the Würzburg Physico-Medical Society in December 1895. The publication of these mysterious rays set off a frenzy as many other physicists and scientists they abandoned what they were doing and immersed themselves in these extraordinary new discoveries. Once the study was finished the published X-rays were advertised for a wide range of uses. Within one month of the publication of the Roentgens study, Dr. Gil... in the middle of the article... ensures that radiation protection activities are carried out in accordance with licensee-approved procedures and regulatory requirements." (NCR) Safety from radiation is something to take very seriously. It has been shown that overuse of radiation can cause burns and hair loss in the applied area. It has even gone as far as contributing to death how much they can cure carcinomas, is something for Strict safety guidelines should always be followed with the simple three-step process involving using short exposure times, staying at least six feet away from the X-ray tube during exposure, and using safety aprons. suitable lead for shielding, you can reduce your exposure to almost zero. Wearing the film badge further improves your protection as you can monitor the amount of radiation you have been exposed to, as it is checked monthly..
