patient radiation protection
before exposure
customize prescribing dental images upon need for every patient
using proper equipment to decrease radiation
Total filtration
collimation
position indication device "PID"
during exposure
thyroid collar
lead apron
digital sensors or fast films
beam alignment devices
film holding device
exposure factor selection
KV= 60-80, Milliamperage=6-8 and shortest exposure time
proper technique
retake of any image must be avoided at all times!
after exposure
proper receptor handling
proper film processing/image retrieval
radiation monitoring badge
- recommended for both intra & extra- oral - effective lead shield should be 0.25mm at least or equivalent
the dental radiographer must avoid the primary beam
distance & position recommendation
stand at least 6 feet (2 meters) away from x-ray, or use a protective barrier
position 90-135 degree angle to the beam
shielding recommendation
protective barriers
minimum aluminum filtration required for machine operating
at or below 70KV = 1.5 mm Al
above 70KV = 2.5 mm Al
most effective method of reducing a patient's radiation exposure
if not available use fast films; f-speed or insight
operator protection
protector guideline
radiation monitoring
equipment monitoring for leakage
personal monitoring
recommended for intra-oral RGs only
