Radon is _ emitter and being radioactive is used in _ treatment in radiotherapy.
Correct answer: B. α, cancer
- A. β, cancer
- B. α, cancer
- C. α, kidney stone
- D. β, kidney stone
Explanation
Radon emits alpha particles that are used for therapeutic purposes to treat cancer. Radon is a gas and as a radioactive element, it is used in the treatment of cancer. It emits alpha, beta, and gamma rays that can damage or destroy cancer cells. Radon is not used in the treatment of kidney stones. Therefore, option B is the correct answer.

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
