QM Fundamentals Flashcards
What is the function of a QM?
Support rad work in your area or others
Conduct rad surveys
Assist in casualty responses
What are the QM survey limits for radiation?
Less than 100 mR/hr
What are the QM survey limits for loose surface contamination?
Less than:
10,000 pCi/100cm2 beta-gamma (ACP and MFP)
1,000 pCi/100cm2 alpha (U)
200 pCi/100cm2 alpha (TRU)
What are the QM survey limits for loose surface contamination within a glovebox?
Less than:
25,000 pCi/100cm2 beta-gamma (ACP and MFP)
2,500 pCi/100cm2 alpha (U)
500 pCi/100cm2 alpha (TRU)
Can QMs direct radiological surveys?
Nope! (RML has an exception with TM operators)
What is the purpose of the Radiological Deficiency Reports (RDR) system?
Identify/document rad deficiencies
Obtain corrective action
Determine root cause
Develop actions to prevent recurrence
Collect data for trend analysis
Prevent small problems from becoming big problems
What are some examples of deficiencies that should be documented as RDRs?
Violations of LAB-RC-0288
Violations of local procedures
Poor work practices
Improperly marked rad material
Damage to containment
Holes in bags
Avoidable exposure
What is a curie?
Amount of radioactivity equal to 3.7 x 10^10 disintegrations per second
Define radioactive material (RAM).
Equipment, parts, and materials that potentially have been exposed to beta-gamma or alpha contamination, or a neutron flux
Can QMs release RAM to no controls?
No
When must audible response be used on meters?
Surveying areas with small intense beams of radiation
Searching for fixed
Trying to find highest contamination area
Alpha measurements
Performing low radiation level evaluations
Using NP-2 on lowest scale
Surveying personnel
What is the decision level concentration (DLC)?
Concentration of a radionuclide above which a decision is made that a detectable amount of radioactivity is present with a five percent probability of erroneously reporting detectable radioactivity when none is present
For the following conditions, does the DLC increase or decrease?
Decrease in background?
Increase in counting time?
Decrease in sample size?
Decreases
Decreases
Increases
What are required characteristics of a radiological survey map?
Facility ID #
Applicable control system
Location
Date/time
Reason for survey
Meters/probes used
Sketch/description
Rad postings of area
Procedure and step number
Remarks
Signature
What is the one situation where QM survey limits do not apply?
Casualty response, under cognizance of RCT
