2.
The maximum permissible limit of Al+3 in Tc-99m eluate is set by?
3.
The quality control procedure known as survey meter calibration is usually performed by:
4.
All of the following single photon emission computed tomography (SPECT) quality control procedures can be performed by the technologist EXCEPT:
5.
Spatial resolution and spatial linearity of a gamma-camera is assessed with a 4-quadrant bar phantom which consists of four sectors of lead bars and intervening plastic strips:
6.
The dose calibrator’s ability to measure accurately a range of low-activity doses to high-activity doses is called:
7.
The quality control procedure performed on the dose calibrator with all the dose configurations used in the nuclear medicine department is called:
8.
Which of the following is a gas-filled radiation survey instrument?
9.
When tested Tc-99m sulfur colloid kit with TLC for free Tc-99m, the technologist noted: strip with free Tc-99m migrated to the solvent front reads 650 cpm, and strip containing Tc-99m sulfur colloid remaining at the point of origin reads 18350 cpm. What is the radiopharmaceutical impurity of this sulfur colloid kit?
10.
When performing daily intrinsic floods, a point source of Tc-99m is placed five crystal dimensions away and centered over the detector. A point source should produce a measured counting rate not greater than:
