Survey Meter General
This is the first thing you do when you turn on the survey meter for each use.
What is the battery
How often is linearity performed?
What is quarterly
How often is constancy performed?
What is Daily
How often is accuracy performed?
What is annually
When is geometry performed?
What is at installation, when it is moved, and repaired
This quality control is performed before each use and uses a long lived source found on the side of the meter
What is constancy
This is a faster way to perform the linearity check and takes minutes as opposed to days.
What is the Calicheck
What sources are used to perform constancy?
What is Cs-137 and Co-57
How many times do you have to assay each source before averaging the results?
What is three times
This isotope is used to test geometry.
What is Tc99
This isotope is used as the constancy check source
What is Co57
How often do you have to assay when performing traditional linearity check?
What is 2 to 3 hours for 2 to 3 days
When during the day is constancy performed?
What is morning
True or False: when performing accuracy you only use Co57 and Tc99
What is FALSE
What are we ensuring is being checked when performing geometry.
What is to make sure isotope activity is consistent in different volumes and containers
This percentage is acceptable for constancy QC.
What is +/-10%
What are the colors used to perform the Calicheck?
What is ROY-G-BIV
True or False: There is a specific order in which you have to perform the constancy quality control.
What is FALSE
What is the acceptable percent range for accuracy?
What is +/-10%
True of False: If a technologist puts 5ml of Tc in a 10ml syringe, and 1.5 ml in a 3ml syringe, this an accurate test of geometry
The Survey meter just broke and we had to get a new one. What are the QC's that need to be performed?
What is battery check, constancy, and calibration
What materials do you need to perform a successful Calicheck?
What are the attenuation tubes, dose calibrator, and a Tc99 source
True or False; You must check the voltage of your dose calibrator
What is True
True or False: When performing Accuracy the DC will tell you if you have the wrong check source.
False
What is the correction factor (CF) equation?
CF= activity at any volume/ activity at 3 mL
