Understanding Alpha, Beta, and Gamma Radiation

Which type of radiation has the highest ionizing power but the lowest penetrating power?

• X-ray radiation

• Beta radiation

• Gamma radiation

• Alpha radiation

During alpha decay, what happens to the atomic number of the nucleus?

• It remains the same

• It decreases by four

• It decreases by two

• It increases by two

What is the charge of an alpha particle?

• Positive two

• Zero

• Positive one

• Negative one

In beta decay, what particle is emitted when a neutron turns into a proton?

• Gamma ray

• Electron

• Positron

• Alpha particle

What is the role of neutrinos in beta decay?

• They stabilize the nucleus

• They increase the mass of the nucleus

• They are emitted alongside electrons or positrons

• They balance the charge

Which type of radiation is a photon with no charge?

• Gamma radiation

• Beta radiation

• Alpha radiation

• Neutron radiation

What happens to the nucleus during gamma decay?

• It remains unchanged

• It gains neutrons

• It loses protons

• It loses electrons

How does an alpha particle move in a magnetic field compared to a beta particle?

• In a smaller circle

• In a larger circle

• In a straight line

• In the opposite direction

Which particle is unaffected by a magnetic field?

• Beta particle

• Alpha particle

• Neutron

• Gamma particle

What rule is used to determine the motion of charged particles in a magnetic field?

• Coulomb's law

• Left-hand rule

• Right-hand rule

• Newton's third law
