CSA Cohort XII

Which of the following is an example of ionizing radiation?

• Laser Beams

• X-rays

• Visible Light

• Electric Current

Which of the following are sources of occupational exposure to ionzing radiation that you may encounter in the field?

• Equipment that produces radiation, like x-ray machines

• Customer Facilities

• Electrical Circuit Panels

• PET or SPECT sources

Which of the following are naturally occuring sources of ionzing radiation?

• Cosmic Radiation (from space)

• Nuclear Power Plants

• Terrestrial Radiation (from Earth)

• Vibranium

What are the possible outcomes when radiation interacts with matter?

• Total Absorption

• Complete Penetration

• Partial Absorption

• All of the Above

TRUE or FALSE: When radiation interacts with cells in the human body, DNA can either be unaffected, repair itself completely, or pass on mutations.

• TRUE

• FALSE

What is the Siemens Annual Exposure Limit for radiation workers? (Answers in millirem)

• 20 mrem

• 500 mrem

• 100 mrem

• 5000 mrem

____, distance, and shielding are the three main principles of ALARA to reduce occupational exposure to radiation.

To practice ALARA when working around radiation, I should:

• Maximize time spent near radiation sources

• Minimize distance from radiation sources

• Leave my dosimeter badge in my car when working around x-ray systems

• Use available and appropriate shielding.

TRUE or FALSE: As a CSA, I am allowed to work with radioactive material sources as long as I wear my dosimeter and complete the Learn4U training.

• TRUE

• FALSE

X-ray service work may require registration in certain states. What are some key points to remember about registration?

• Personnel registration is required in 13 states prior to any work that affects beam output

• I can accompany a registered CSE on service calls to replace tubes or collimators

• Registration only applies to radiation producing machines like x-rays

• I am not allowed to work in the same room as an x-ray machine until I am registered
