True or False: Radiation can only come from artificial sources.

• A. True
• B. False
• C. Sometimes true
• D. Non-applicable

Answer: (B)

Radiation can originate from both artificial and natural sources, making the statement false. Natural sources of radiation include cosmic rays from outer space, terrestrial radiation from soil and rocks, and radon gas that can accumulate in homes. On the other hand, artificial sources are human-made, such as X-ray machines, nuclear power plants, or certain medical therapies. This dual origin of radiation highlights the importance of understanding both types when assessing exposure risks and implementing safety measures. Therefore, the idea that radiation can only come from artificial sources is incorrect, reinforcing the choice of 'false' as the correct answer.
