GENERIC RADIATION WORKER TRAINING
FINAL PAPER 2026 TESTED QUESTIONS
WITH FULL SOLUTION GRADED A+
●● The three parts of an atom is:.
Answer: Protons, neutrons, and electrons.
●● The center of the atom is ?.
Answer: The nucleus
●● What parts of an atom are in the nucleus?.
Answer: protons and neutrons
●● What part of an atom orbits the nucleus?.
Answer: electrons
●● Protons have what type of charge?.
Answer: positive charge
●● Electrons have what kind of charge?.
Answer: negative charge
,●● Neutrons have what kind of charge?.
Answer: no charge
●● Unstable (Radioactive) Atoms.
Answer: an atom that has excess energy.
●● radioactive decay.
Answer: The process that an atom goes through to become stable is
radioactive decay
●● ionizing radiation.
Answer: Energy or small particles, emitted from radioactive materials,
which can cause chemical or physical damage when they deposit energy
in living tissue
●● Radioactive material.
Answer: A large collection of radioactive atoms
●● Radioactive material gives off radiation in the form of ?.
Answer: Particles and waves
●● radioactive contamination.
, Answer: When radioactive material is in a place it is not supposed to be
in
●● Radiation.
Answer: A burst of energy as either particles or waves, given off by a
radioactive atom.
●● The excess energy of an unstable atom is called ?.
Answer: Radiation
●● Fission.
Answer: The splitting of an atom
●● Alpha Radiation.
Answer: Very large compared to other types of radiation, can not go very
far, very thin materials such as paper easily shield it
●● Beta Radiation.
Answer: a small negative charged particle that is ejected from the
nucleus, smaller and has less charge than alpha, a concern mainly when
contaminated reactor systems and components. Can be shield by plastic
or thin metal
●● Gamma Radiation.
