VERSION
Atom -ANSWER✅✅✅Smallest particle of an element
Protons -ANSWER✅✅✅Positively charged particles
Neutron -ANSWER✅✅✅no charge
Electron -ANSWER✅✅✅negatively charged particle
nuclear fuel -ANSWER✅✅✅atoms in the fuel split releasing large quantities of
radiation and energy. the energy released heats up the water to make steam
plant components -ANSWER✅✅✅parts and pieces used to generate electricity
Activated Corrosion Products -ANSWER✅✅✅non radioactive material that becomes
radioactive after exposure to neutron radiation in reactor
Reactor Operations -ANSWER✅✅✅operating reactor and equipment that supports it
can change radiation levels in the plant
reactor coolant -ANSWER✅✅✅water that flows in and around reactor
Alpha -ANSWER✅✅✅penetrating-low
shielding -paper/clothing
hazard - inhaled/ingested
,found- any radioactive material in plant activities that disturb the materials are likely to
cause alpha emitters
Beta -ANSWER✅✅✅penetrating-medium s
shielding-plastic/wood
hazard- skin dose & dose to lens of the eyes
found- very common throughout plant
Gamma -ANSWER✅✅✅penetrating- high
shielding-lead, steel, and concrete
hazard- highest due to penetrating ability and common occurrence in organs.
found-very common throughout plant
Neutron -ANSWER✅✅✅Penetrating-high
Shield-water, lead, steel, concrete
hazard-dose to entire body if exposed
found-only in or near operation reactor
TEDE -ANSWER✅✅✅Total Effective Dose Equivalent
whole body dose, contains critical organs, comes from radiation sources outside the
body (most common) & inside your body (very small amount)
Rem (millirem) -ANSWER✅✅✅measured radiation exposed in people
biological effects -ANSWER✅✅✅effects of radiation on cells: no damage, damage and
repaired, cell death, mutated and survives
Chronic radiation exposure -ANSWER✅✅✅exposed to a small amount of radiation
over long period of time. health risk, measured by loss of life, 1 rem/year; 30 years - 51
days lost
acute radiation exposure -ANSWER✅✅✅exposed to a high amount of radiation over a
short period of time (sunburn). Risk depending on dose (rem) nothing could happen, get
very sick, or even death. workers DO NOT receive acute exposure
somatic effects -ANSWER✅✅✅effects of radiation exposure that show up in the
person exposed to radiation
genetic radiation -ANSWER✅✅✅if reproductive cells are damaged it is passed on to
next generation
somatic effect -ANSWER✅✅✅cancer, leukemia, other sickness
genetic effects -ANSWER✅✅✅cancer, birth defects
, younger people are -ANSWER✅✅✅more sensitive to exposure than older people
NRC Form 4 -ANSWER✅✅✅documents your occupational exposure. must be
completed before radiation exposure
TEDE dose limit -ANSWER✅✅✅limit guideline
TEDE: 5 rem/yr 2rem/yr
lens & eye: 15 rem/yr 12 rem/yr
skin: 50rem/yr 40 rem/yr
extremities: 50 rem/yt. 40 rem/yr
consequence for exceeding dose limits -ANSWER✅✅✅health effects, fines against
plant by NRC, disciplinary actions, increased NRC regulatory oversight, and jail time
who do you contact if dose limits are approached? -ANSWER✅✅✅RP
Declared pregnant worker -ANSWER✅✅✅pregnant worker who voluntarily informed
the plant in writing of pregnancy and true estimated date of conception
Planned special exposure -ANSWER✅✅✅an authorized exposure that is separate
from and in addition to the annual dose limit- can only be received once in career
ALARA -ANSWER✅✅✅As Low As Reasonably Achievable
Program: follow procedures and policies, written/verbal instructions from RP, know dose
rate in your area, know current dose, comply with admin or federal dose limit, give
suggestions
Time -ANSWER✅✅✅the more time you spend working the more dose you get
distance -ANSWER✅✅✅the closer you are to something the more dose
move away when talking , or use long tools
Shielding -ANSWER✅✅✅reduces dose
lead blankets, walls, paper, plastic, water etc
Dosimetry -ANSWER✅✅✅device accurately measures the amount of radiation a
person is exposed to
DLR -ANSWER✅✅✅Dosimeter of Legal Records
SRD -ANSWER✅✅✅Self Reading Dosimeter
DLR (dosimeter or legal records) -ANSWER✅✅✅provide permanent record of your
dose, very accurate, have no electronic or moving parts, can't be read by user
