patient radiation protection

Ensuring the safety of both dental radiographers and patients involves a multi-faceted approach to radiation protection. Radiographers must avoid direct exposure to the primary beam by standing at least six feet away or using protective barriers and positioning themselves at a 90-135 degree angle relative to the beam.

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

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
