What electrical charge does a proton carry?
A. Negative
B. Neutral
C. Positive
D. Variable
Correct Answer: C. Positive
Rationale: A proton is a subatomic particle found in the nucleus of an atom and carries a
positive electrical charge. This positive charge balances the negative charge of electrons.
Protons, neutrons, and electrons together make up what structure?
A. Molecule
B. Atom
C. Compound
D. Cell
Correct Answer: B. Atom
Rationale: An atom is the basic unit of matter and is composed of three main subatomic
particles: protons, neutrons, and electrons.
Which type of radiation loses energy with each ionization, travels only a few feet in air,
and can penetrate paper but not a thin sheet of aluminum?
A. Alpha particle
B. Beta particle
C. Gamma ray
D. Neutron
Correct Answer: B. Beta particle
Rationale: Beta particles have moderate penetrating power. They can pass through paper
but are stopped by thin aluminum and lose energy as they cause ionization.
,Which form of radiation travels at the speed of light, has no electrical charge, and is the
least ionizing?
A. Alpha particle
B. Beta particle
C. Gamma ray
D. Proton
Correct Answer: C. Gamma ray
Rationale: Gamma rays are high-energy electromagnetic waves with no mass or charge.
They travel at the speed of light and are less ionizing than alpha or beta particles.
What best describes chronic exposure to radiation?
A. Exposure from a single event
B. Short-term high-dose exposure
C. Continuous exposure over a long period
D. Exposure that causes immediate illness
Correct Answer: C. Continuous exposure over a long period
Rationale: Chronic radiation exposure occurs over an extended time, usually at low doses,
and may lead to long-term biological effects.
Which category of biological effects of ionizing radiation can affect an embryo?
A. Somatic
B. Acute
C. Genetic
D. Occupational
Correct Answer: C. Genetic
Rationale: Genetic effects involve damage to reproductive cells and can affect embryos or
future generations.
Background radiation combined with occupational radiation exposure is known as what?
A. Absorbed dose
B. Effective dose
C. Total exposure
D. Genetic dose
,Correct Answer: C. Total exposure
Rationale: Total exposure includes natural background radiation plus any radiation
received through occupational or medical sources.
What term describes the amount of radiation dose received by an employee whose duties
involve working with radiation or radioactive materials?
A. Background dose
B. Absorbed dose
C. Occupational dose
D. Genetic dose
Correct Answer: C. Occupational dose
Rationale: Occupational dose refers specifically to radiation exposure received as part of a
person’s job responsibilities.
Which group represents the three essential components of a Radiation Safety Program?
A. Monitoring, shielding, and exposure
B. Training, recordkeeping, and reporting
C. Dosimetry, equipment, and staffing
D. Protection, prevention, and policy
Correct Answer: B. Training, recordkeeping, and reporting
Rationale: A Radiation Safety Program relies on proper training of personnel, accurate
recordkeeping of exposure, and required reporting to ensure compliance and safety.
Which particle has a positive charge and is found in the nucleus of an atom?
A. Electron
B. Neutron
C. Proton
D. Alpha particle
Correct Answer: C
Rationale: Protons carry a positive charge and are located in the nucleus.
What component of an atom has a negative charge?
A. Proton
B. Neutron
C. Electron
D. Nucleus
, Correct Answer: C
Rationale: Electrons orbit the nucleus and carry a negative charge.
Which radiation type has moderate penetration and can be stopped by aluminum?
A. Alpha
B. Beta
C. Gamma
D. Neutron
Correct Answer: B
Rationale: Beta particles can penetrate paper but are stopped by thin metal.
Which radiation type is most penetrating?
A. Alpha
B. Beta
C. Gamma
D. Electron
Correct Answer: C
Rationale: Gamma rays penetrate deeply and require dense shielding.
Which material is most effective for shielding gamma radiation?
A. Paper
B. Plastic
C. Aluminum
D. Lead
Correct Answer: D
Rationale: Dense materials like lead effectively reduce gamma radiation.
Which radiation is most dangerous when inhaled or ingested?
A. Gamma
B. Beta
C. Alpha
D. X-ray
Correct Answer: C
Rationale: Alpha particles cause severe damage when inside the body.
