Question 1: The Joint Commission Revised Requirements for Diagnostic Imaging Services effective date is: |
Reference: | The Joint Commission Prepublication Requirement Revised Requirements for Diagnostic Imaging Services, January 9, 2015.
|
Choice A: | July 1, 2014 |
Choice B: | July 1, 2015 |
Choice C: | July 1, 2016 |
Choice D: | July 1, 2017 |
Question 2: NCRP 147 recommends simulating a full workload of kVp exposures with the radiographic equipment to determine the adequacy of radiation barriers? |
Reference: | NCRP Report #147, 2014, 108 |
Choice A: | True. |
Choice B: | False. |
Question 3: The Joint Commission Revised Requirements for Diagnostic Imaging Services requires that a radiation protection survey be conducted: |
Reference: | The Joint Commission Prepublication Requirement Revised Requirements for Diagnostic Imaging Services, January 9, 2015. |
Choice A: | Prior to clinical use. |
Choice B: | Prior to installation of equipment. |
Choice C: | Within 30 days of the start of clinical use. |
Choice D: | Within the first year of clinical operation. |
Question 4: What is the acceptable operating condition for the door leading into a linear accelerator treatment room? |
Reference: | NCRP Report 151: Structural Shielding Design and Evaluation for Megavoltage X-ray and Gamma-Ray Radiotherapy Facilities (2005), pages 98-99. |
Choice A: | Opening the door has no effect on beam production. |
Choice B: | Opening the door interrupts the beam “on” status causing the beam to go to the “off” condition. |
Choice C: | Closing the Door automatically reinitiates the beam to the “on” condition. |
Choice D: | Beam can be restarted with the door in the open condition to allow treatment to be completed. |
Question 5: To evaluate the adequacy of a primary barrier, one must measure the instantaneous dose rate with the maximum energy photon beam: |
Reference: | NCRP Report 151: Structural Shielding Design and Evaluation for Megavoltage X-ray and Gamma-Ray Radiotherapy Facilities (2005), pages 100 - 102.
|
Choice A: | Oriented toward the primary barrier with no phantom in the beam. |
Choice B: | Oriented toward the primary barrier with an adult equivalent phantom in the beam. |
Choice C: | Used primarily for IMRT only oriented toward the primary barrier with no phantom in the beam. |
Choice D: | Used primarily for IMRT only oriented toward the primary barrier with an adult equivalent phantom in the beam. |
Question 6: To determine compliance with applicable permissible dose limits, which of the following values is appropriate? |
Reference: | NCRP Report 151: Structural Shielding Design and Evaluation for Megavoltage X-ray and Gamma-Ray Radiotherapy Facilities (2005), pages 103-104. |
Choice A: | The measured Instantaneous Dose Rate. |
Choice B: | The TADR (Time Averaged Dose Rate). |
Choice C: | The IDE (Integrated Dose Equivalent). |
Choice D: | The IDR (Instantaneous Dose Rate Equivalent). |
