◍ Gamma Radiation:Penetrating Ability:Shielded by:Type Hazard:Major
Source:Additional Info:.
Answer: Definition- Highly penetrating burst of energy emitted from an
unstable atom. PA: Very high, penetrates the whole bodySB: Very dense
material; usually lead and steelTH: Whole-body dose hazardMS: Fission,
fission products, and activation products in the primary system pipingAI:
Has no mass or electrical charge - it is pure energy
◍ Radioactive Waste.
Answer: Material that must be disposed due to radioactivity.
◍ Plant-Specific Dosimeters.
Answer: Each plant site will have their own dosimeters and will instruct you
on their use.
◍ Unplanned radiation exposure.
Answer: Unexpected radiation dose exceeding safety limits.
◍ Regarding discrete radioactive particles state The hazards.
Answer: If a discrete particle gets on your skin, the legal dose limit could be
exceeded. Additionally, if a discrete particle enters your body, it can cause
an internal dose.
◍ ALARA Committee.
Answer: Group overseeing ALARA program implementation.
◍ Shielding to Reduce Dose.
, Answer: Explain how shielding may be used to reduce dose, and state
methods to implement this concept.
◍ Hot Spot.
Answer: A localized source of radiation that is much greater than the general
background radiation level (components with contact readings more than
100 MREM/hr and more than five times the general area dose rates)
typically found where corrosion products (crud) my accumulate, such as
piping elbows, low-point drained, and others
◍ Internal deposition.
Answer: The process by which radioactive material (contamination) enters
and stays in the body
◍ Job Scope Changes.
Answer: Alterations to planned work activities affecting radiation.
◍ Contamination Control.
Answer: Preventing the spread of radioactive contamination. Contamination
control programs result in minimal spread of contamination through the
facility. No contamination should leave the radiologically controlled areas.
◍ Committed Effective Dose Equivalent (CEDE).
Answer: Total internal dose from radioactive materials.
◍ Committed.
Answer: Refers to dose received from radioactive material that is inside the
body
◍ Alpha Contamination.
Answer: Hidden alpha radiation under corrosion layers.
◍ Define High radiation area.
Answer: An accessible area in which a person could receive a whole-body
dose greater than 100 millirem in one hour (100 mrem/hr) at 30 centimeters
(about 12 inches) from the source.
◍ Radioactive Decay.
, Answer: when atoms release energy in the form of waves or particles to
become stable.
◍ Radiological Area: High Radiation Area.
Answer: Is an accessible area in which a person could receive a whole-body
dose in excess of 100 millirem in one hour (100 millirem/hr) at 30
centimeters (about 12 inches) from the source of radiation.
◍ End of Assignment for DLRs.
Answer: The point at which a user must return their DLR to the dosimetry
group after completing their job.
◍ Dose savings.
Answer: The reduction in radiation exposure achieved by using shielding.
◍ TEDE Radiation limit is.
Answer: 5 rem per year, guideline is 2 rem per year
◍ Radiation Exposure Risks.
Answer: Chronic and acute radiation exposures have different associated
risks.
◍ Beta.
Answer: *Penetrating ability: travels a few feet in the air.* Shielded by:
lightweight plastic or aluminum.*Type hazard: eyes and skin are most
susceptible to beta radiation. It can be aninternal hazard.* Major source:
most beta particles come from activated corrosion and
fissionproducts.*Additional information: personnel must work close to a
beta source to receivemuch dose.*is a concern mainly when contaminated
reactor systems and components are open, such as valves that are
disassembled for repair. Corrosion products frequently collect in plant
components, so opening them can create a significant beta radiation hazard.
◍ ALARA Program Components.
Answer: * prejob ALARA reviews and prejob briefings* job planning to
include worker experience and lessons learned*training mockups (models of
a structure or area that are used outside radiologicalareas for study,
, demonstration, and practice)*good radiological work practices such as
temporary shielding* engineering controls such as ventilation and system
cleanup
◍ Electron.
Answer: Negatively charged particle orbiting the nucleus.
◍ Health Effects from High Doses.
Answer: Scientific studies show an increased chance of health effects such
as cancer from high doses delivered over a relatively short period.
◍ Prenatal Exposure.
Answer: The possible effects of radiation on an unborn child due to prenatal
exposure.
◍ ALARA Tools.
Answer: Time, distance, and shielding methods to reduce dose.
◍ Radiation Work Permit.
Answer: Document outlining safety instructions for radiation work.
◍ Fuel and Reactor Operations.
Answer: 1.) Fission creates radioactive "fission products" (such as
radioactive iodine)2.) Neutronsnot absorbed atoms become a radiation
hazard as long as the fission process is occurring.3.) When the reactor is
shut down, and fission slows, neutron radiation is not a problem.
◍ Area Survey Map.
Answer: Map indicating contamination and radiation levels.
◍ Radiation Dose Limits.
Answer: Regulatory limits set for the maximum amount of radiation
exposure allowed for workers.
◍ Your Responsibilities with RWPs.
Answer: *Failure to follow the requirements of the RWP may result in
increased dose, spread of contamination, or other radiological
problems.*Failure to comply could also result in the plant being fined or
