• William Conrad Rankin, X Radiation

• Marie Curie, Radioactive Rays

• Albert Einstein, Light Radiation

What is the primary difference between x-rays and visible light?

• X-rays have longer wavelengths than visible light.

• X-rays are generated by radioactive decay.

• X-rays are a type of particle radiation.

• X-rays have shorter wavelengths and are outside the visible spectrum.

How are x-rays generated in an x-ray tube?

• By heating a filament to emit light.

• By reflecting light off a mirror.

• By accelerating electrons with high voltage and decelerating them abruptly.

• By using radioactive materials to emit radiation.

What is a common use of x-rays in airports?

• To detect impurities in groceries.

• To illuminate and inspect baggage contents.

• To check the quality of car tires.

• To measure the germination capacity of seeds.

What is the unit of measurement for the effective dose of ionizing radiation?
