Video Note: Effects of Ionizing Radiation&Protection For Operator Flashcards
What is the focus of the presentation?
The presentation is about the effects of ionizing radiation on operator and patient protection.
Who is the presentation geared toward?
The presentation is geared toward the Dental Assisting student.
What is ionization?
Ionization is when ions are produced in cellular structures of tissues when exposed to dental x-rays or to x-rays radiation.
What factors affect biological effects of ionizing radiation?
The biological effects depend on the amount of radiation, the frequency of exposure, the sensitivity of the cells, and the cumulative effect of repeated exposure.
How can operator and patient protection be minimized?
Protection can be minimized through x-ray equipment, shielding, and proper exposing techniques.
What is important for equipment and shielding?
Dental x-ray units should be in good working order with periodic inspections and quality control protocols.
What type of film should be used if not using digital sensors?
If using film, ultra speed film or f speed film should be used.
What is required for patient protection?
Patients are required to wear a lead or lead equivalent apron to protect them from radiation.
Why is a thyroid collar important?
A thyroid collar is important because the thyroid is very sensitive to radiation.
What distance should operators maintain from the radiation source?
Operators must be at least six feet away from the source of radiation.
What does ALARA stand for?
ALARA stands for ‘as low as reasonably achievable.’
What is the maximum permissible dose for dental or medical operators?
The maximum permissible dose is 50 millisieverts per year.
What is the maximum permissible dose for the general public?
The maximum permissible dose for the general public is 5 millisieverts per year.
What is the purpose of radiology monitoring?
Radiology monitoring is done to measure the radiation exposure of the radiographer.
What is a film badge?
A film badge contains radiosensitive film that is tested to measure radiation exposure.
What is the unit of measure for radiation exposure?
The unit of measure for radiation exposure is called the sievert.
What should be done if radiographic images are not of diagnostic quality?
Quality assurance and control programs should be in place to review and improve radiographic images.
What is required in some states regarding radiation protection?
In some states, a radiation protection program must be documented for operator and patient protection.
