1. X-Rays are
a) A type of radiation that originates in the nucleus of an atom.
b) Of the same concern as sunlight exposure on a hot, clear day.
c) Easily stopped by plastic or paper.
d) Penetrating radiations with enough energy to ionize atoms deep within body tissues.
2. Radiation exposure to operators of x-ray machines and bystanders can result from
a) Exposure only to the primary beam.
b) Exposure to the primary beam and scattered radiation due to poor shielding or defective equipment.
c) The high voltage terminals.
d) incident “ghost” x-rays after machine is turned off.
3. The most serious radiation injury from analytical x-rays arise from
a) Accidents that develop during warm-up of the equipment.
b) From electrical insulation in the high-voltage system.
c) Having hands near the open beam path during operation.
d) Placing the target and material at an acute angle.
4. The three basic radiation exposure minimization factors are
a) Time, distance, and shielding.
b) Shielding, lead aprons, and P.I. Training.
c) Distance, labeling, and security.
d) Distance, voltage, and amperage.
5. The California Department of Public Health, Radiologic Health Branch
a) Can inspect any x-ray device and query operations at any time without advance notice.
b) Registers each x-ray device and charges a fee for doing so.
c) Has itsphone numbers and basic workplace safety information on an official poster in each x-ray machine site.
d) All of the above.
6. Upon discovery of a problem with potential radiation exposure / leakage with an x-ray device, the operator must first
a) Leave the device running and go seek help.
b) Turn off power at the emergency cut off switch.
c) Call the P.I. and leave a voicemail.
d) Call the RHB phone number on the poster.
7. An x-ray device may be brought onto the CSULB campus, providing
a) It is being donated by another California State Campus program.
b) It is presently not operationaland CSULB Radiation Safetydoesn’t find out about it.
c) Advance approval is granted by CSULB Radiation Safety and the device is registered with Cal RHB within 30 days of acquisition.
d) The unit is a safe cabinet type and is installed by a factory technician.
8. An x-ray safety interlock
a) Is a key switch that ensures that only authorized key-carrying personnel can operate the machine.
b) Is an alarm system on the x-ray room that alerts University Police of an unauthorized entry.
c) Is a special hook that holds the sample in place so that the reflected x-rays are directed awayfrom the operator.
d) Is a switch or switches that cut power to the x-ray when the shielding doors are opened even slightly.
9. Medical Diagnostic X-Ray Machines
a) Are medical devices exempt from the Health Department Regulations.
b) Maybe operated by any medical doctor or registered nurse.
c) Are serviced and inspected every three years by certified technicians.
d) None of the above.
10. The CSULB-Authorized P.I. who supervises x-ray equipment
a) May authorize equipment use by any trusted grad student.
b) Need not provide machine-specific documented training as long as the device is used in a regularly-scheduled class.
c) Is allowed to perform repairs on the x-ray - producing components and shielding without RSO permission.
d) shall provide and document machine-specific training and maintain a machine use-log.
11. An x-ray device already authorized for CSULB use may be relocated
a) Only with written approval of the RSO
b) Anywhere on campus because 1250 Bellflower Blvd. is the address on our registration
documents.
c) Only within given departments e.g. Geological Sciences
d) Only after calling the State RHB phone number on the official poster and getting state
approval over the phone.
12. “X-Ray ON” warning lights
a) Are not required on older machines that did not come from the factory with such a feature.
b) Must turn “ON” automatically whenever x-rays are being produced.
c) May be located anywhere in the x-ray room.
d) Can be an operator-activated with an ON/OFF switch at the x-ray control panel.
13. X-Ray Dosimeter badges and rings
a) Must always be worn by x-ray operators.
b) Protect operators from radiation damage after unplanned dose.
c) Measure and document radiation dose accrued by operators.
d) Can be shared so that everyone has a recorded dose record.
14. Radiation Safety concerns should be addressed to
a) The x-ray device supervisor.
b) The CSULB Radiation Safety Office.
c) The Nuclear regulatory commission
d) Experienced graduate students.
15. The use – log for each x-ray device
a) Must be filled out only once per week during the semester.
b) Must be completed for each operation of the unit, including training and diagnostic checks.
c) Must be completed, photocopied, and sent to the RSO each week.
d) Only needs to be used by undergraduate operators.
