Cs-137 has a half-life of 30 years and produces: 133 keV gamma ray 388 keV gamma ray 662 keV gamma ray 637 keV gamma ray None 2. The battery check, sealed source check, and calibration are three different quality control procedures performed to ensure proper operation of the: Geiger-Mueller detector Glucose meter Well counter Thyroid probe None 3. The dose calibrator’s ability to measure accurately a range of low-activity doses to high-activity doses is called: Linearity Accuracy Constancy Geometry None 4. The quality control procedure performed on the dose calibrator with all the dose configurations used in the nuclear medicine department is called: Constancy Geometry Linearity Accuracy None 5. All of the following quality control (QC) tests are performed in nuclear medicine department to assess the reproducibility of radiation counter EXCEPT: The relative error The chi-squared test The reliability factor The constancy test None 6. The center of rotation (COR) of gamma-cameras is a key quality control procedure performed to assess capability of the nuclear medicine cameras to perform: Dual phase scanning Planar imaging SPECT imaging Dynamic scanning None 7. The quality control procedure known as survey meter calibration is usually performed by: The physicist The radiation safety officer The lead technologist The technologist None 8. Which of the following is a gas-filled radiation survey instrument? Thermoluminescent dosimeter (TLD). Pocket ionization chamber. Optically stimulated luminescence (OSL) dosimeter. Geiger-muller counters. None 9. The shield and the decay method are two different approaches to evaluate: Effective dose measurement Half-value layer thickness Dose calibrator linearity Gamma Camera linearity None 10.
