Radioactivity is the process by which unstable atomic nuclei lose energy by emitting radiation.

Radioactivity is the emission of alpha particles only.

Radioactivity refers to the energy production in nuclear reactors.

Radioactivity is the conversion of protons into neutrons.

Radioisotopes are primarily used for sterilizing surgical equipment.

Radioisotopes are often used in medical imaging and treatment, such as using iodine-131 to treat thyroid conditions.

Radioisotopes are used in accelerators for particle physics experiments.

Radioisotopes are used to enhance the flavor of foods.

In beta decay, the nucleus loses two protons and decreases its mass number by 4.

In beta decay, a neutron in the nucleus is transformed into a proton, increasing the atomic number by 1, but the mass number remains unchanged.

In beta decay, the nucleus absorbs an electron and converts a proton into a neutron.

In beta decay, an electron is emitted, and the nucleus remains unchanged.

Gamma radiation is a form of electromagnetic radiation of high energy and short wavelength, emitted from the nucleus.

Gamma radiation consists of neutrinos that originate from the sun.

Gamma radiation involves the emission of alpha particles only.

Gamma radiation refers to the high-energy photons emitted from an electron cloud.

Nuclear stability is the constant emission of radiation by an atom.

Nuclear stability refers to the ability of a nucleus to remain unchanged over time, typically influenced by its ratio of protons to neutrons.

Nuclear stability means the nucleus undergoes rapid transformation at all times.

Nuclear stability is determined solely by the number of electrons in an atom.
