GENERIC RADIATION WORKER TRAINING
ACTUAL TEST PAPER 2026 QUESTIONS
WITH SOLUTIONS GRADED A+
●● What are the three parts that an atom consists of?.
Answer: Protons, neutrons, and electrons
●● Protons.
Answer: Part of the nucleus of the atom. They have a positive charge.
●● Nucleus.
Answer: The center of the atom
●● Neutrons.
Answer: Part of the nucleus of the atom. They do NOT have any charge.
●● Electrons.
Answer: Small negatively charged particles that orbit around the nucleus
of the atom.
●● What are the three primary components of an atom?.
Answer: Protons, Neutrons, Electrons
,●● Radioactive Material.
Answer: A large collection of radioactive atoms
●● Radioactive Contamination.
Answer: When radioactive material is in a place it is not supposed to be
in (or is not wanted), such as on the floor
●● Where does Radioactive Material gives off radiation?.
Answer: Anywhere
●● Radiation Protection Personnel.
Answer: Use signs and barriers to warn you about conditions in your
work area
●● Unstable (radioactive) Atoms.
Answer: An Atom that has excess energy. Also known as a Radioactive
Atom
●● Radioactive Decay.
Answer: The process that an atom goes through to become stable
●● Radiation.
,Answer: A burst of energy as either particles or waves, given off by a
radioactive atom during the radioactive decay process.
●● What does it mean when an unstable atom goes through radioactive
decay?.
Answer: It will give off its excess energy as radiation
●● Where is most of the radiation at a nuclear plant?.
Answer: Inside the reactor
●● What are the sources of radiation in a nuclear plant?.
Answer: Reactor Operations, Plant Component, Reactor Coolant,
Fission Products, Activated Corrosion Products, Reactor Fuel
●● Reactor Operations.
Answer: Operating the nuclear reactor can change radiation levels in
some areas of a plant
●● Plant Components.
Answer: Layers of radioactive material can build up over time or
become trapped in pipes, pumps, filters, valves and other equipment
●● Reactor Coolant.
, Answer: The water that circulates through the reactor becomes
radioactive over time and can be a source of radiation
●● Fission Products.
Answer: Pin hole leaks in the metal sheathing around the fuel can allow
radioactive gases to escape into the reactor. They can then be carried
through steam and water to other areas of the plant.
●● Activated Corrosion Products.
Answer: Bits of metal and other debris can be carried by water into the
reactor. In the reactor they become radioactive through a process called
"activation".
●● Reactor Fuel.
Answer: Nuclear fuel is a source of radiation in a plant. Personnel are
not normally exposed to the fuel because it is shielded.
●● Fission.
Answer: The splitting of Atoms
●● What is created in the fission process?.
Answer: Heat and Radiation
●● Fission Products.
