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