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
