Abstract
Purpose: In DRLs 2020, in addition to the fluoroscopic dose rate, air kerma at the patient entrance reference point (Ka,r) and air kerma-area product (PKA) by types of medical treatment and diseases were set as DRL quantity. We surveyed the current equipment setting dose at each facility and the exposure dose in clinical practice. We considered the optimal DRL classification of Ka,r and PKA for the next DRLs update.
Methods: We conducted a questionnaire survey of 428 facilities in Japan with angiography devices and analyzed the obtained angiography dose data.
Results: Fluoroscopic dose rate, Ka,r, and PKA were lower values compared to past studies and DRLs 2020 data, and significant differences were observed in Ka,r and PKA by procedure.
Conclusion: Equipment setting doses have been optimized at each facility, and it is expected that radiological protection will be optimized by setting DRL values that reflect the current situation.
