Radiographers are responsible for producing good image quality by providing the lowest possible
radiation dose, by the As Low As Reasonably Achievable (ALARA) principle. One of the ALARA
principle methods in a radiographic examination is to implement optimization efforts by knowing the
DRL. The research method is a quantitative description using the measurement method radiation
output as a way for radiographers to estimate the radiation dose received by patients, then
socialization to 17 radiographers about DRL as an effort to optimize radiographic examinations using
the results of percentage pre and post-test as indicators of success > 90%, with conclusions about
the increase in radiographers' understanding of DRL as an effort to optimize the value paired t-test
p< 0,05. The results of the radiation dose estimation using the method radiation output by
determining the equation power function y = 0,0005x2.9242. From the results, the pre-test found the
number of correct answers with a percentage of 59%. While for the results of the post-test number
of correct answers that percentage is 94%. The results of the test to increase the understanding of
the radiographer as an optimization effort based on the statistical test paired t-test p-value < 0,001
So it is certain that radiographers have increased understanding after socialization about DRL as an
effort to optimize the radiographic examination
