PROCEDURE TITLE
WHAT IS "RADIATION AND CONTAMINATION SURVEYS"?
Section 5.2
Name three types of surveys needed to evaluate radiological conditions in the workplace.
What is Radiation, Contamination, and Airborne.
Section 6.1.3
If entering areas with unknown dose rates, use the BLANK anticipated scale and adjust as needed.
What is highest?
Section 6.1.8
Notify BLANK of any changes in area postings.
What is "RP Supervision"?
Section 6.2.2
When verifying the absence of contamination via direct frisk, ensure background does not exceed the following: (Hint 2 criteria)
What is
1) <200 cpm to detect with a pancake GM detector.
2) Background sufficient to meet required MDA <20dpm/100cm2 for alpha.
Sec. 4.3
If an event causes an increase in dose rates by greater than a factor of 1000, RP shall contact BLANK
Who is the Shift Manager? (for their consideration to declare an Unusual Event.)
Section 5.3.2
These are performed to verify that radiological conditions have not extended into areas that are not posted and controlled.
What are Routine surveys?
Section 6.1.7
Name the 4 heights at which dose rates are measured when evaluating an area in close proximity to a source of high radiation where a worker may be positioned.
What is "knees, waist, chest, head"?
Section 6.1.11
While performing a radiation survey you identify an area that you suspect radiation streaming. You have evaluated the dose rates, source, and configuration. What is your next step?
What is "Notify RP Supervision to assess the need for mitigating actions"?
Section 6.4
Large Area Wipes provide a qualitative assessment that is used to verify the absence of removable contamination in a relatively large area; large area smears have a detection threshold but they are not...
What is "used to quantify removable contamination levels"?
Section 5.3
Areas and frequencies for routine surveys are established by BLANK
What are Site Procedures?
This is the first step in the process of performing radiological surveys.
What is evaluate previous surveys to understand expected conditions?
Section 6.1.11
When are surveys performed in areas greater than 7 ft above the floor?
What is "if ladders, scaffolds, or platforms are in place to gain access"?
Section 6.5.4
You are surveying a Discrete Radioactive Particle (DRP) using an ion chamber. Your OW/CW ratio is <10. This normally indicates
What is a "Fuel Fragment"?
Section 6.8.1
List the 3 instances in which immediate notification to RP supervision is required by NISP-RP-002.
What is
1)Changes in radiological conditions that require changes in postings or RWPs.
2) Dose rates greater than the site limit outside an RCA.
3) Discovery of radioactive material outside the RCA.
Section 5.3.4
Routine surveys are only performed in LHRAs if.....
routine access is required or if directed by RP supervision.
Section 6.1.7
If dose rates exceed 100 mRem/hr between the knees and the head close to a source of high radiation levels determine if
What is "a dose gradient exists"?
Section 6.6.3
For Alpha Level I areas, what is the criteria determining the number of smears analyzed for alpha?
What is "at least 10%, or 3 at a minimum, of the smears with the higher contamination levels, when Beta/Gamma contamination > 100,000 dpm/100cm2.
Section 6.9.5
You are documenting a survey of a contaminated system breach. List the required measurements to be recorded. (Hint: 5 elements)
What is
1)Contact and 30 cm gamma measurements on exposed system internals.
2)Contact and 30 cm beta dose rates if contamination levels exceed 500,000 dpm/100 cm2.
3) Air sample results during the breach as required by RP supervision.
4) Smear results from the exposed internal surface.
5) Smear results from the area around the breached component.
Section 6.5.4
You are surveying a DRP using an ion chamber. Your OW/CW ratio is >30. This normally indicates...
What is "a corrosion product"?
Section 6.1.1
Two methods to consider to minimize dose while performing a survey.
What are
1) Use of extendable probes
2) Standing behind shielding materials or structures
Section 6.1.7.c
If the highest dose rate is not at chest level, record dose rates as follows: (Hint: 2 steps)
What is
1)Record the chest dose rate on the survey record along with the locations of higher dose rates.
2)Annotate each dose rate based on body location (knees, waist, chest, head) per Attachment 2
Section 6.9.5
What type of Radiation surveys are used to determine Hot Spots?
What is "Contact and 30 cm measurements"?
Section 6.4.4
Direct frisk of a Large area wipe yields >100 ncpm above background. What is your next step?
What is "perform a disc smear survey (100 cm2)"?
Section 6.7.3
If the βγ/α Ratio is less than or equal to 50 and the total alpha activity is greater than or equal to 20 dpm/100 cm2, verify...
What is "that an alpha frisker is available and the area has been posted to require alpha frisking per NISP-RP-004, Radiological Postingand Labeling.
