Radiation Basics

What are the three main types of radiation?

• zeta radiation

• alpha radiation, beta radiation, gamma radiation

• delta radiation

• epsilon radiation

Which type of radiation has the highest energy?

• X-ray radiation

• Gamma radiation

• Alpha radiation

• Beta radiation

What is the primary source of background radiation?

• Alien technology

• Natural sources

• Man-made sources

• Underground nuclear testing

How does alpha radiation differ from beta radiation?

• Alpha radiation is not a form of radiation.

• Beta radiation consists of alpha particles.

• Alpha radiation consists of beta particles.

• Alpha radiation consists of alpha particles (helium nuclei), while beta radiation consists of beta particles (high-energy electrons or positrons).

What type of radiation can penetrate the human body?

• Alpha radiation

• Gamma radiation

• Ultraviolet radiation

• X-ray radiation

Which type of radiation is commonly used in medical imaging?

• Gamma rays

• Ultraviolet rays

• Microwaves

• X-rays

What are the units used to measure radiation exposure?

• Curie

• Sievert

• Roentgen (R), Rad, and Rem

• Gray

How does gamma radiation differ from alpha and beta radiation?

• Gamma radiation is stopped by a piece of paper, while alpha and beta radiation can penetrate it.

• Gamma radiation is positively charged, while alpha and beta radiation are negatively charged.

• Gamma radiation is electromagnetic, while alpha and beta radiation are particles.

• Gamma radiation has a mass, while alpha and beta radiation are massless.

What are some common sources of man-made radiation?

• Medical imaging, nuclear power plants, industrial gauges, consumer products like smoke detectors

• Solar panels

• Microwave ovens

• Cell phone towers

How can exposure to radiation be minimized?

• Ignore distance, prolong time, wear heavy clothing

• Decrease distance, increase time, avoid shielding materials

• Increase distance, reduce time, and use shielding materials.

• Stay close, spend more time, use reflective materials
