1. Atom - ANSWER ✔ The smallest part of an element that retains the
characteristics of the element
2. What are the three parts that an atom consists of? - ANSWER ✔ Protons,
neutrons, and electrons
3. Protons - ANSWER ✔ Part of the nucleus of the atom. They have a positive
charge.
4. Nucleus - ANSWER ✔ The center of the atom
5. Neutrons - ANSWER ✔ Part of the nucleus of the atom. They do NOT have
any charge.
6. Electrons - ANSWER ✔ Small negatively charged particles that orbit around
the nucleus of the atom.
,7. What are the three primary components of an atom? - ANSWER ✔ Protons,
Neutrons, Electrons
8. Radioactive Material - ANSWER ✔ A large collection of radioactive atoms
9. Radioactive Contamination - ANSWER ✔ When radioactive material is in a
place it is not supposed to be in (or is not wanted), such as on the floor
10.Where does Radioactive Material gives off radiation? - ANSWER ✔
Anywhere
11.Radiation Protection Personnel - ANSWER ✔ Use signs and barriers to
warn you about conditions in your work area
12.Unstable (radioactive) Atoms - ANSWER ✔ An Atom that has excess
energy. Also known as a Radioactive Atom
13.What are the two main types of contamination monitors at any plant? -
ANSWER ✔ Frisker and a Personnel Contamination Monitor (PCM)
14.Frisker - ANSWER ✔ Use a hand-held probe coupled with a meter that you
use to check yourself for contamination.
15.What should you do before you pick up a frisker probe? - ANSWER ✔
Check to ensure the frisker is turned on, Set to the X1 scale and The Display
is less than 200 counts per minute (cpm)
,16.When should you contact RP when using a frisker? - ANSWER ✔ If it
increases by more than 100 cpm and stays above that level
17.How should you leave the frisker? - ANSWER ✔ With the probe facing
upward, ready for the next worker
18.What should you do if the PCM alarms? - ANSWER ✔ Exit out the same
way you entered. DO NOT exit into a clean area, Notify RP for assistance
19.TEM - ANSWER ✔ Tool Equipment Monitors
20.How to recognize Contaminated Areas? - ANSWER ✔ Signs with the words
"contaminated Area", Step-off Pads on floor at Exit/Entrance point, Yellow
and Magenta rope or ribbon at boundary
21.Signs and Barriers - ANSWER ✔ Used to identify contaminated areas. They
are yellow with a magenta or black three-bladed symbol
22.What will you need to enter a contaminated area? - ANSWER ✔ Protective
clothing (PC) to prevent contamination from getting on you and your
clothing
23.What are Alpha contaminated areas designated as? - ANSWER ✔ Level II
or III with Level III areas having the highest risk and most protective RP
controls
, 24.In what situations require you to exit a contaminated area? - ANSWER ✔
You tear your PCs, You suffer a cut, abrasion, or other type of open wound,
your PCs get wet from a leak, spill, or profuse sweating, Your dosimeter is
alarming or is lost, or you observe any other abnormal condition, You are
directed by RP personnel
25.Radioactive Contamination - ANSWER ✔ Radioactive material in an
unwanted location
26.Loose Contamination - ANSWER ✔ Can easily be spread from one area to
another.
27.Fixed Radioactive Cotamination - ANSWER ✔ is not easily removed or
spread around
28.Discrete Radioactive Particles - ANSWER ✔ Tiny specks of highly
radioactive material
29.Disintegrations Per Minute (DPM) - ANSWER ✔ A rate measurement of
radiation. Each interaction reflects one disintegration. The average number
of interactions per minute is calculated and is expressed as counts per
minute. Since no instrument can detect all the disintegrations an estimate of
the total number is calculated based on the ability of the instrument
30.Alpha Radiation - ANSWER ✔ Penetrating Ability: Least penetrating ability
of the 4 types; travels approximately 1 inch in air
Shielded by: A piece of paper, lightweight clothing, or outer layer of skin
Type Hazard: Internal hazard - can result in a high dose to sensitive organs
Major Source: Nuclear Fuel
