B+Wilhelm+Roentgen

=__Isotope and Radioactivity__= = = = Wilhelm Roentgen = = = = = = = =Explanation of interesting facts: (how used/works.experiments/discoveries)=
 * 1) November 8, 1895, Roentgen discovered and produced the electromagnetic radiation of **X-rays** or otherwise known as //Roentgen rays.// Roentgen refused to have the rays named after him.
 * 2) Before his discovery, Roentgen was investigating the various types of vacuum tube equipment when an electrical discharge is passed through them. During his experiment with one of the vacuum tubes and cathode rays, he found the invisible cathode rays caused a fluorescent effect on a cardboard screen painted in barium platinocyanide, Ba[Pt(CN)4], occur when placed close to the aluminum window used in the experiment. The fluorescent effect led him to discover x-rays.
 * 3) Two weeks after the discovery of X-rays, Roentgen took his first X-ray picture of his wife's hand, Anna Bertha, and saw the skeleton of her hand and she exclaimed, "I have seen my death"
 * 4) Roentgen was the very first person to be awarded the Nobel Prize in Physics after his discovery of the X-rays
 * 1) Roentgen was the very first person to be awarded the Nobel Prize in Physics after his discovery of the X-rays

=3 Advantages of using X-rays:=

1. In medicine, X-rays are used to locate an abnormality inside the human body, like fractures, growth of tumor, etc.

2. A portable x-ray unit produced and useful anywhere.

3. Using X-rays are cheap unlike using MRI or CT scans.

=3 Disadvantages of using X-rays:= 1. The information obtained are in lesser detail.

2. People are exposed to ionizing radiation that is harmful to humans.

3. Can cause cancer.

=Is the radioactive isotope/radiation/discovery still used today? Explain= X-rays are still being used today. Majorly used in medical units to reveal the skeleton and other internal structures within the human body, search for abnormalities in the human body, and used in dental imaging. X-rays are also used to examine the cargo of airplane passengers transporting illegal cargo like bombs, dangerous weapons, or illegal substances. It is also used in construction to find faults or structural deficits missed by the eyes of construction workers or architects when building a structure, a building, or a bridge.
