9a Radioactivity Quiz physics alevel edexcel

Gamma decay results in the emission of:

• An electron

• A helium nucleus

• A neutron

• Electromagnetic radiation

Beta decay involves the emission of:

• An electron

• A helium nucleus

• A neutron

• A gamma ray

Dangers from nuclear radiations include:

• Radiation sickness and increased cancer risk

• Enhanced physical strength

• Improved cognitive function

• Accelerated aging process

Nuclear binding energy is the energy required to:

• Break apart a nucleus into its constituent nucleons

• Combine nucleons to form a nucleus

• Convert mass into energy during nuclear reactions

• Produce radiation from a nucleus

Background radiation refers to:

• Radiation emitted by nuclear power plants

• Radiation present in the environment from natural and artificial sources

• Radiation emitted during nuclear fission

• Radiation emitted during nuclear fusion

Nuclear fusion involves the:

• Splitting of heavy nuclei into lighter nuclei

• Combination of lighter nuclei to form heavier nuclei

• Release of energy from a nucleus

• Conversion of mass into energy during nuclear reactions

Nuclear fission is the process of:

• Combining two or more nuclei to form a heavier nucleus

• Breaking apart a heavy nucleus into lighter nuclei

• Releasing energy from a nucleus

• Converting mass into energy during nuclear reactions

Alpha decay occurs when a nucleus emits:

• An electron

• A helium nucleus

• A neutron

• A gamma ray

The decay constant represents:

• The rate at which radioactive nuclei decay

• The amount of radiation emitted during decay

• The energy released during decay

• The time taken for half of the radioactive nuclei to decay

The binding energy per nucleon is calculated by dividing the total nuclear binding energy by the:

• Number of protons in the nucleus

• Total number of nucleons in the nucleus

• Number of neutrons in the nucleus

• Mass of the nucleus in kilograms
