The present study aimed to propose local diagnostic reference levels (DRLs) formulated by calculating entrance surface doses for general radiography at 20 facilities of Aichi prefecture in Japan, by comparing these values with DRLs established in Japan in 2015 (DRLs 2015) and assessing radiation dose differences among facilities. X-ray outputs (half-value layer and air kerma) of each facility were measured with a non-invasive type of detector. The results were employed to formulate local DRLs based on the 75th percentiles of dose distributions. These local DRLs were lower than the DRLs 2015 for all examinations. If proposed local DRLs from other 46 prefectures can be collected, this paper can be used to benefit the next effort to draft better DRL for Japan.
