(a)
Interpretation:
The definition of term radioactive is to be stated and the explanation of the given statement is to be stated.
Concept introduction:
The radioactive decay is a process which involves the emission of radiation by an unstable atomic nucleus. The atomic nucleus loses its energy during radioactive decay. The process of radioactive decay is spontaneous.
Answer to Problem 10.1E
An unstable substance which emits high energy radiations by decay of atom is known as radioactive substance. Beta rays itself are not radioactive but they are the product of radioactive decay.
Explanation of Solution
An unstable substance which emits high energy radiations by decay process of atom is known as radioactive substance. Alpha, beta and gamma rays are emitted during radioactive decay of a substance. Beta rays itself are not radioactive but they are the product of radioactive decay.

Answer to Problem 10.1E
The given statement is incorrect because Radon is an unstable element and undergoes radioactive decay.
Explanation of Solution
The given statement that radon is a stable radioactive substance is not correct. Radon is an unstable element and undergoes radioactive decay. Radon decays to polonium by emitting alpha and gamma rays.
The given statement is incorrect because radon is an unstable element and undergoes radioactive decay.
