The Electromagnetic Spectrum: X-Ray By: Tishana Dorsey 4 A

Physical Description ● ● ● X-rays are a form of electromagnetic radiation. The frequency of an x-ray is 3 x 10^16 Hz. The wavelength ranges from 0. 01 to 10 nanometers The Quantum energy ranges from 100 e. V to 100 ke. V. The Wave speed is 3 x 10^8 m/s or 300, 000 meters per second.

Uses of X-rays ● ● The main use of x-rays is in medicine. X-rays are used in hospitals to produce photographs of bones which can be checked for breaks or fractures. Mammograms use x-rays to look for breast cancer. Chest X-rays spot pneumonia

Determination of the source of the wave…. . Where could this wave possibly come from……? ● A German Physicist, Wilhelm Roentgen, discovered a new form of radiation in 1895. He called it x-radiation because he had no idea what this radiation was. It had the ability to pass through materials that absorb visible light,

Can X-rays help or harm the world generally…. ? Actually, X-rays are both harmful and beneficial…. . . BENEFITS ● ● Treat malign tumors before it spreads throughout the human body. Help radiologists identify cracks, infections, injury, and abnormal bones. Help identify bone cancer. X-rays help in locating alien objects inside the bones or around them. Hazards ● ● ● X-rays makes our blood cells to have higher level of hydrogen peroxide which could cause cell damage. There is a higher risk of getting cancer from X-rays. The X-rays are able to change the base of the DNA causing a mutation.

Occupation exposure limit. . . How long can a person be exposed to x-radiation…… ● ● ● Persons under the age of 18 years are also limited to 0. 5 rem/year. The dose limit to non-radiation workers and members of the public are two percent of the annual occupational dose limit. Therefore, a non-radiation worker can receive a whole body dose of no more that 0. 1 rem/year from industrial ionizing radiation. Eye dose: 15 rems (0. 15 sv) Shallow dose: whole body (skin) 50 rems (0. 50 sv) Total Organ dose: any organ 50 rems (0. 50 sv)

Fun Facts about…. X-Rays! Did you know……. . ● ● ● ● X-rays were first discovered over 100 years ago and were quickly applied to medical diagnostic use. The “X” in X-ray means unknown. Wilhelm Röntgen was experimenting with some vacuum tubes when he made the discovery. ( It’s crazy how you discover new things in everyday life. ) He was awarded the Nobel Prize in Physics for his invention in 1901. X-rays can kill cancer cells, but also it can kill healthy cells, so one must be cautious when using x-radiation. X-rays are the oldest and most useful medical technolog. Y. When you have an x-ray, you MUST wear a lead apron to protect certain parts of the body.
