GENERIC RADIATION WORKER
TRAINING PRACTICE EXAMINATION
2026 QUESTIONS WITH ANSWERS
GRADED A+
◍ Radiation Characteristics.
Answer: Different types of radiation have unique properties.
◍ Loose Contamination.
Answer: Can easily be spread from one area to another.
◍ ALARA Responsibilities.
Answer: Responsibilities that individuals have as part of the ALARA
Program to keep dose as low as reasonably achievable.
◍ Internal Organs Dose Limit.
Answer: 50 rem/year for internal organ exposure.
◍ Define TEDE.
Answer: Total Effective Dose Equivalent. This is the total of a person's
external dose and internal dose
◍ Radiation exposure limit.
Answer: The maximum amount of radiation a worker is allowed to receive
in a given time frame.
◍ Activated Corrosion Products.
Answer: 1.) As Corrosion products are carried through the reactor by the
coolant they become activated (made radioactive).2.)They settle in low spots
in the RCS or get stuck around valves and other components and become a
source of radiation exposure
,◍ Smear.
Answer: Cloth used to sample surface contamination.
◍ Reactor Design.
Answer: Structure intended to contain radioactive fission products.
◍ Alpha Radiation (Eye Interaction).
Answer: Alpha radiation cannot penetrate into the interior of the eye
including the lens.
◍ Methods to limit internal deposition.
Answer: Includes respiratory protection and engineering controls.
◍ Airborne Radioactivity Area.
Answer: An area in which airborne radioactivity exists in excessof 1
Derived Air Concentration (DAC) or 12 DAC-hours in a week. (More on
DACslater.)
◍ What can be one of the first indications of a serious radiological problem?.
Answer: Radiological Alarms
◍ What is the Penetration ability of Alpha Radiation?.
Answer: Low
◍ State the actions to be taken if administrative dose limits are being
approached..
Answer: Do not exceed these limits. If you are approaching a limit or
guideline, contact the radiation protection staff before going further.
◍ Pre-Job Brief.
Answer: A meeting before a job to discuss safety measures and potential
hazards.
◍ Administrative Guidelines.
Answer: Dose administrative guidelines set by utilities. These guidelines are
lower than the federal limits and are used to help control dose increase and
prevent exceeding federal limits.
◍ Dose Reduction Practices.
, Answer: Methods include time, distance, and shielding.
◍ About Your Tools and Equipment.
Answer: Tools, equipment, and materials can become contaminated during
work on contaminated systems and components.The plant Maintenance
Department has a tool room inside the radiologically controlled area,
commonly referred to as the "hot tool crib" or "hot tool room." It is stocked
with most of the common tools needed for work on any system or
component. Use tools issued from there for work in radiologically controlled
areas and return the tools when you are finished.Don't take new or
uncontaminated tools into radiologically controlled areas unless they are
absolutely necessary for work and they are not available in the hot tool
room.
◍ Radiation.
Answer: A burst of energy as either particles or waves, given off by a
radioactive atom during the radioactive decay process.
◍ Why is contamination controlled?.
Answer: Good radiological work practices are needed to control
contamination. Without control, contamination could be spread to places
away from the plant such as homes, cars, and public places. This could
result in unmonitored radiation dose and possible exposure to public. Once
detected, it would take a lot of work to clean up the uncontrolled area,
monitor to make sure everything was decontaminated, and dispose of the
radioactive waste generated
◍ Extremities.
Answer: Hands and lower arms (including the elbows) as well as feet and
lower legs (including the knees). DOES NOT INCLUDE VITAL ORGANS
◍ Control of contaminated tools.
Answer: Minimizing materials contaminated and using RCA tool issue
points.
◍ What can SRDs measure?.
, Answer: Gamma Radiation (some measure neutron radiation)
◍ ALARA.
Answer: As Low As Reasonably Achievable.
◍ Describe Electrons.
Answer: Electrons are small negatively charged particles that orbit around
the nucleus of the atom.
◍ radioactive contamination.
Answer: When radioactive material is in a place it is not supposed to be in
◍ Recognize the methods used to determine the amount of radioactive material
deposited in the body.
Answer: A whole-body counter directly measures the level of radioactivity
in your body and what type of radioactive material is present.Bioassays
determine the amount of radioactive material by analyzing urine and/or fecal
samples. Determining internal alpha contamination may require repetitive
bioassay samples along with whole body counts.
◍ Contaminated Area Signs.
Answer: Yellow/magenta signs with a three-bladed symbol.
◍ Guidelines.
Answer: Are used by the nuclear industry to stay well within the federal
laws.
◍ Radiation safety protocols.
Answer: Procedures established to protect workers from excessive radiation
exposure.
◍ Declared Pregnant Worker.
Answer: Pregnant women have an option for a lower dose limit. To get the
lower limit they must declare their pregnancy.
◍ Plant Conditions.
Answer: Factors that may increase airborne radioactivity risk.
◍ Alpha.
