◍ Section- Types of Radiation.Statements- Four main types of radiation are
found at _______ _____ ______. Each is different and has characteristics
that are _________ to remember:___________ _______ (what can the
radiation go through)_________ _______ (what can stop or reduce the
radiation)_________ ______ (for example what part of the body is
exposed)______ ________ ( what gives off the radiation)Comparison of
Types of Radiation and PenetrationShielding: Alpha: _____ Beta: _______
Gamma: ____ Neutron: _______.
Answer: Nuclear Power Plants, ImportantPenetrating Ability, Shielding
Methods, Exposure Hazard, Major SourcesPaper, Plastic, Lead, Concrete
◍ Example calculation.
Answer: If you have a 2000 millirem guideline and a current dose of 200
millirem, with a dose rate of 200 millirem/hr, you can stay for 9 hours.
◍ List the sources of radiation in the plant Fuel.
Answer: Nuclear fuel is a source of radiation in a plant. Personnel are not
normally exposed to the fuel because it is shielded.
◍ A number on the map inside a circle.
Answer: The location of a smear
◍ dose.
Answer: is the amount of radiation absorbed by the body or a particular
organ. Dose is total radiation exposure received
,◍ Dosimeter of Legal Record (DLR).
Answer: Used to keep up with our official dose. It can not be read by
looking at it, it must be sent off to a lab to be read.
◍ ALARA Planning strategies.
Answer: Before entering the radiological work area, talk to your co-workers
about the job and what you expect to do, Make sure the tools you will need
are available and in good working order, Tell RP about your plans
◍ Common Practices to Reduce Dose.
Answer: Time, distance, and shielding are common practices used to reduce
radiation dose.
◍ Cell Mutation.
Answer: Damage to the cell from radiation exposure may result in mutation
but not necessarily cell death.
◍ Define Genetic Effects of radiation exposure.
Answer: Appear in future children of an individual who received the dose.
The chances of their occurring are very small even with radiation exposure
much higher than that experienced by nuclear workers. NOTE: The
probability of occupational exposure producing a genetic mutation in a
worker's offspring is extremely remote.
◍ Dose Limit.
Answer: Maximum allowable radiation dose for workers.
◍ Radioactive Waste.
Answer: Material no longer usable due to radioactivity.
◍ Can shielding reduce dose?.
Answer: Permanent and temporary shielding in the plant can reduce the dose
you receive by reducing the intensity of a radiation field. Lead Blankets are
often used as shielding b/c they can shield alpha, beta, and gamma radiation.
If dose required to install lead blanket exceeds the dose savings, it doesn't
make ALARA sense.
,◍ Mockups.
Answer: Practice setups to reduce time in radiation areas.
◍ ALI = 5 REM, which you would get fro breathing 1 DAC for how many
hours?.
Answer: 2000
◍ State the plant administrative limits and guidelines for radiation dose..
Answer: Federal Regulation 10 CFR 20 states that no licensee (nuclear
plant) shall allow any person to receive a total occupational dose greater
than the legal limits. The limit is 5 rem per year. The guideline is 2 rem per
year.
◍ Neutron Radiation (Characteristics).
Answer: Neutron radiation is highly energetic neutrons ejected from the
nucleus.
◍ Glove Liners.
Answer: Inner gloves used for additional contamination protection.
◍ NRC Form-4.
Answer: A federal form that documents your occupational exposure
◍ Millirem.
Answer: One-thousandth of a rem, a radiation dose unit.
◍ What are the four types of Radiation?.
Answer: Alpha, Gamma, Beta, Neutron
◍ Energy Release.
Answer: Energy in the form of radiation is released when an atom splits as
part of the fission process.
◍ Penetration of Gamma Radiation.
Answer: Gamma radiation can penetrate through equipment and piping, and
travels further than the other types.
◍ Practice the ALARA concept.
, Answer: Engaging in practices that minimize radiation exposure.
◍ Radioactive Decay.
Answer: The process that an unstable (radioactive) atom goes through to
become stable by giving off excess energy as radiation.
◍ Dosimetry Personnel.
Answer: Staff managing dosimeter distribution and records.
◍ What are the 4 major pathways to loose contamination getting into your
body?.
Answer: Inhalation - breath it in, ingestion - swallow it, Absorption - enter
through the skin, Open wounds or sores - gets into wound
◍ Radiological Conditions Change.
Answer: Rapid shifts in radiation levels during work.
◍ Radiation exposure effects.
Answer: The impact of radiation on individuals, which can be either genetic
or somatic.
◍ Time to Reduce Dose.
Answer: Explain how time may be used to reduce dose, and state methods to
implement this concept.
◍ Low Dose Area.
Answer: A notification to you of the lowest dose rate in the work area.
◍ Exposure Hazard.
Answer: The likelihood of receiving radiation exposure from a particular
type of radiation.
◍ Extract information from RWP.
Answer: Extract information from an RWP (for example, protective
clothing, dosimetry, special instructions).
◍ (RCS).
Answer: reactor coolant system
