Atoms -ANSWER✅✅✅The building blocks of all matter. The smallest part of an
element that retains the characteristics of the element.
The three parts of an atom is: -ANSWER✅✅✅Protons, neutrons, and electrons.
The center of the atom is ? -ANSWER✅✅✅The nucleus
What parts of an atom are in the nucleus? -ANSWER✅✅✅protons and neutrons
What part of an atom orbits the nucleus? -ANSWER✅✅✅electrons
Protons have what type of charge? -ANSWER✅✅✅positive charge
Electrons have what kind of charge? -ANSWER✅✅✅negative charge
Neutrons have what kind of charge? -ANSWER✅✅✅no charge
Unstable (Radioactive) Atoms -ANSWER✅✅✅an atom that has excess energy.
radioactive decay -ANSWER✅✅✅The process that an atom goes through to become
stable is radioactive decay
ionizing radiation -ANSWER✅✅✅Energy or small particles, emitted from radioactive
materials, which can cause chemical or physical damage when they deposit energy in
living tissue
Radioactive material -ANSWER✅✅✅A large collection of radioactive atoms
,Radioactive material gives off radiation in the form of ? -ANSWER✅✅✅Particles and
waves
radioactive contamination -ANSWER✅✅✅When radioactive material is in a place it is
not supposed to be in
Radiation -ANSWER✅✅✅A burst of energy as either particles or waves, given off by a
radioactive atom.
The excess energy of an unstable atom is called ? -ANSWER✅✅✅Radiation
Fission -ANSWER✅✅✅The splitting of an atom
Alpha Radiation -ANSWER✅✅✅Very large compared to other types of radiation, can
not go very far, very thin materials such as paper easily shield it
Beta Radiation -ANSWER✅✅✅a small negative charged particle that is ejected from
the nucleus, smaller and has less charge than alpha, a concern mainly when
contaminated reactor systems and components. Can be shield by plastic or thin metal
Gamma Radiation -ANSWER✅✅✅Can be shield by thick materials of led, concrete, or
steel
Neutron Radiation -ANSWER✅✅✅Has to be slowed down with water first and then
can be easily shielded with dense material like lead, steal, or concrete
Which radiation is the most common and can penetrate through metal? -
ANSWER✅✅✅Gamma
Common sources of radiation in a nuclear plant are? -ANSWER✅✅✅Fuel, plant
components, corrosion and activation products, and reactor operations
Dose Rate -ANSWER✅✅✅how fast you would be receiving radiation exposure.
Measured in millirem or rem per hour
Dose -ANSWER✅✅✅The amount of radiation you were exposed to
Agency that governs the nuclear industry -ANSWER✅✅✅Nuclear Regulatory
Commission (NRC)
Cell Mutation -ANSWER✅✅✅One of the biological effects that can result from
radiation damage to a cell. A mutated cell survives but has been altered
, Chronic Radiation Exposure -ANSWER✅✅✅when you are exposed to a small amount
of radiation over a long period. Damaged may be prolonged.... cancer
Acute Radiation Exposure -ANSWER✅✅✅when you are exposed to high levels of
radiation over a short term. Damage is immediate.
Somatic Effects -ANSWER✅✅✅Effects of radiation exposure that show up in the
person exposed to radiation
Genetic Effects of Radiation -ANSWER✅✅✅If reproductive cells are damaged and it is
passed on to the next generation
Radiosensitivity -ANSWER✅✅✅Radiation has a greater effect on cells that have a
higher rate of reproduction. Younger people are most sensitive to exposure
Radiation Protection (RP-Rad Pro) -ANSWER✅✅✅Responsible for implementing
station policies, procedures, and programs.
RP Staff -ANSWER✅✅✅Experts on radiation exposure
Total Effective Dose Equivalent (TEDE) -ANSWER✅✅✅Radiation dose to your body
containing the vital organs
TEDE Radiation limit is -ANSWER✅✅✅5 rem per year, guideline is 2 rem per year
Extremites -ANSWER✅✅✅the arms, legs, hands, and feet
Limit is 50 rem per year guideline is 40 rem per year
Skin -ANSWER✅✅✅Skin of the whole body
Limit is 50 rem per year, guideline is 40 rem per year
Lens of the eye -ANSWER✅✅✅15 rem per year, guideline is 12 rem per year
Declared pregnant worker -ANSWER✅✅✅Limit of 500 mil item over the entire term of
pregnancy. Guideline is 450 millirem and not to exceed 50 millirem per month
Planned Special Exposure (PSE) -ANSWER✅✅✅An authorized exposure that is
separate from and in addition to the annual dose limit. Once in a lifetime chance where
you exceed federal radiation limits
You are required to keep your dose ALARA -ANSWER✅✅✅As low as reasonably
achievable
Three common ALARA tools -ANSWER✅✅✅Time
