Answer: radiation

Flashcard 3: In the modern X-ray tube, the _____ is made of tungsten+thorium

Answer: cathode

Flashcard 4: Fast-moving electrons interact with _____ of anode, to produce continuous spectrum radiation, also called as Bremsstrahlung radiation (80%)

Answer: nucleus field

Flashcard 5: When the voltage (kVP) increases, penetration of X-rays _____

Answer: increases

Flashcard 6: _____ are produced when the electron beam decelerates close to the nucleus of the atom in the anode.

Answer: X-rays

Flashcard 7: Optical Coherence Tomography uses the principle of _____

Answer: near-infrared light interferometry

Flashcard 8: <_____ rads/year is the permissible level of radiation

Extra: 

Flashcard 10: The average annual radiation dose received by an individual from all sources (natural + medical) is _____ rad.

Answer: 0.2-0.3

Extra: Natural background radiation accounts for ~0.1-0.2 rad/year, while medical exposures (diagnostic X-rays, etc.) contribute additional dose, totaling an average of approximately 0.2-0.3 rad per year for an individual.
