Atomic And Nuclear Physics - SS3 Physics Past Questions and Answers - page 3
What is gamma decay?
Gamma decay occurs when the nucleus emits a gamma ray, which is a high-energy electromagnetic radiation. Gamma decay does not change the atomic number or mass number of the nucleus.
What is the process that releases energy from the nucleus of an atom?
Nuclear fusion
Nuclear fission
Both A and B
None of the above
Which type of nuclear reaction is responsible for the energy production in the sun and other stars?
Nuclear fusion
Nuclear fission
Radioactive decay
None of the above
What is the name of the particle that is emitted during alpha decay?
Electron
Proton
Neutron
Helium nucleus
Which type of nuclear reaction is used in nuclear power plants to generate electricity?
Nuclear fusion
Nuclear fission
Radioactive decay
None of the above
What is the process by which a radioactive nucleus spontaneously emits a particle and becomes a different nucleus?
Alpha decay
Beta decay
Gamma decay
Neutron decay
What is nuclear fusion?
Nuclear fusion involves combining two light nuclei, such as hydrogen isotopes, to form a heavier nucleus, releasing a large amount of energy in the process. This process powers the sun and other stars and is also being researched as a potential source of clean energy.
What is nuclear fission?
Nuclear fission occurs when a heavy nucleus, such as uranium or plutonium, is bombarded with a neutron and splits into two smaller nuclei, releasing energy in the form of gamma rays, neutrons, and kinetic energy. This process is the basis for nuclear power plants and nuclear weapons.
Which of the following materials is commonly used as a shield against gamma radiation?
Lead
Aluminum
Plastic
Copper
Which of the following is a potential long-term health effect of exposure to ionizing radiation?
Sunburn
Cancer
Headache
Allergy
