Session Title: A Practical Guide to Radiation Safety Surveys
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).
