Full+Body+Scanner+for+Radiation

=__​ Isotope and Radioactivity__= = = =Name of radioactive isotope/electromagnetic radiation/scientist:= = = Full Body CT Scans : The Danger of Radiation =Explanation of interesting facts: (how used/works.experiments/discoveries)= 5. CT scans are so helpful because they show every detail including very small bones as well as surrounding tissues such as muscle and blood vessels. =3 Advantages of using the radioactive isotope/radiation/benefits of discovery=
 * 1) CT scanner fist gun shots of electrons are deflected off a coil, the beans hits a tungsten ring and is reflected through the patient as an x-ray, finally the x-rays hit the patient and gets an image.
 * 2) The CT scan is used to see inside the body and opening it up while an x-ray is used to see through the body
 * 3) The CT scan was invented in 1972 by Doctor Godfrey Hounsfield
 * 4) The full name for a CT scan is Computerized Axial Tomography and is referred to as a CT scan or a CAT scan.

1. With a CT scan doctors are able to see from the scan what they would only be able to see through surgery or an autopsy before the at CT scan was invented.

2. CT scans are very helpful to find caners and tumors in the brain, liver, lungs, and abdominal organs, also to see obstructions in nasal passages and bleeding the the brain.

3. CT scans are realtivly fast and compleatly painless.

=3 Disadvantages of using the radioactive isotope/radiation/discovery:= 1. A full brain CT scan gives off 12 millisieverts of radiation. A sievert is the biological effects of radiation as opposed to the physical aspects, which are characterized by the absorbed dose.

2. 1 in every 1,250 people who has gotten a full boy CT scan will get cancer because of the radiation for the CT.

3. The amount of radiation in one full body CT scan is the same as the amount of radiation received by survivors of the atomic bomb.

=Is the radioactive isotope/radiation/discovery still used today? Explain=

The radioactive CT scanner discovery is still used today because although it emits radiation into the patients body its posotive effects are higher than the negative. A CT scan can help doctors emensly to find cancers and malfunctions in the human boday and CT scans are normally done to one islated part of the body. A fully boday CT scan is what gives the most radiation harm to patients and full body scans are only done when they are absolutly neccisary. I think that the CT scanner should still be used today and for years to come becuase it is a huge building block in medical history that cuts down on the number of sergerys done.
