=Explanation of interesting facts: (how used/works.experiments/discoveries)= = = =3 Advantages of using the radioactive isotope/radiation/benefits of discovery=
 * 1) Airport use full body scanner as a security system.
 * 2) The first full body scanner was invented by Sir Fodfrey Hounsfield in 1972.
 * 3) Full body scanner works within 30 minutes, fastest within 5 to 10 minutes.
 * 4) Before the CT scan starts, all metal objects including jewelry, eyeglasses, dentures and hairpins, that can interfere with CT imaging should be removed.
 * 5) CT scans were first used in medicine in the 1970s.

1. Full body scanner is painless, and the results are accurated.

2. Full body scanner can provide very clear images of all parts of body.

3. CT is less sensitive to patient movement than MRI = = =3 Disadvantages of using the radioactive isotope/radiation/discovery:= 1. Exposed patients to 10 mSv, which is 100 times more than a chest x- ray.

2. Cost a lot of money, about US $ 600 to $3000

3. Pregnant women are not recommended to use full body scanner.

=Is the radioactive isotope/radiation/discovery still used today? Explain= Yes, full body scanner is still use today. It is a very useful equipment, doctors use it to check your body, and airports use it to maintain the security. It is also painless, no radiation will remain in your body after the use, and the results are accurate.
