Which type of radiation can penetrate a few layers of clothing and travel through several feet of air?

• A. Alpha radiation
• B. Gamma radiation
• C. Beta radiation
• D. X-ray radiation

Answer: (C)

Beta radiation is composed of high-energy, high-speed electrons or positrons emitted by certain types of radioactive nuclei. It has greater penetration abilities compared to alpha radiation, which can be stopped by just a piece of paper or skin. Beta particles can penetrate a few layers of clothing and can travel through several feet of air, making them hazardous in certain environments where exposure might occur. Gamma radiation, while also highly penetrating, is more powerful and can pass through thick materials, including concrete and lead. However, it is not the best choice for this specific question, which focuses on the type of radiation that effectively penetrates clothing and a moderately sized air gap without invoking the stronger penetrating power of gamma rays. X-rays are similar to gamma rays in terms of their penetration capabilities, but they are typically generated from electronic sources rather than from radioactive decay, which makes beta radiation the most fitting answer in the context of the question.
