Answer 10

Wilhelm Conrad Roentgen

Question 11

When was the Xray discovered?

Answer 11

November 8 1895

Question 12

Schools Roentgen was a professor at?

Answer 12

Strasbourg, Giessen, Wurzburg, and Munich

Question 13

What aided in the discovery of the Xray?

Answer 13

Cathode Tube

Question 14

How was the X-ray discovered?

Answer 14

Roentgen was doing experiments with a Cathode tube. He wrapped black cardboard around the tube to keep the florescent light from escaping, when suddenly another screen outside the tube was glowing. Invisible rays had passed through the cardboard.

Question 15

Natural Source of Xrays?

Answer 15

Radon gas (radioactive gasses naturally released from rocks, soil, and etc., radioactive elements, and cosmic rays that hit the earth from outerspace.

Question 16

3 effects of Xrays to an object

Answer 16

Collide with electrons, Absorbed, and Scattered

Question 17

If materials are dense/ have high atomic number?

Answer 17

Absorbed

Question 18

Isn’t very dense/low atomic number?

Answer 18

Collide

Question 19

What product Produces Xrays?

Answer 19

Xray Tube

Question 20

3 Steps in Xray Production

Answer 20

Source of Electrons, Acceleration, Deceleration

Question 21

Where are electrons produced?

Answer 21

Cathode Filament

Question 22

A process which is the release of electrons with response to heat

Answer 22

Thermionic Emission

Question 23

What is needed to accelerate the electrons

Answer 23

kVp (kilovoltage P)

Question 24

Creates a strong negative charge in the filament that forces electrons to the positively charged Anode.

Answer 24

kVp (kilovoltage P)

Question 25

What is the anode plate made out of?

Answer 25

Tungsten

Question 26

What happens in Deceleration?

Answer 26

They release their energy as heat, and more importantly, as Xrays.

Question 27

What were its uses in the past?

Answer 27

Used in surgeries, and during the world war was used in detecting bullets.

Question 28

What was the first ever shot of an xray?

Answer 28

Roentgen’s wife’s hand

Question 29

Significance in the present?

Answer 29

Diagnosing cancer, used in medicine, and Xray Imaging.

Question 30

Are Xrays safe?

Answer 30

Sometimes yes, sometimes no. Because it would depend on the exposure/energy emitted.

Question 31

Why recommend an xray in medicine?

Answer 31

Can be used to detect blood vessels, bone cancer, and tumors.

Question 32

Xrays that are not in medicine

Answer 32

Security (Baggage Scanner, Portable Scanners)

Astrophysics (Xray Telescope and Xray CCD Camera and Scanner)
