Facility reference level data

The curves below show the cumulative distributions for the DLP and CTDI_vol  from adult DRL surveys submitted to ARPANSA in 2024. The plots display the percentage of surveys that achieved a facility reference level (FRL) below the dose specified on the x-axis. The blue curve represents all of the submitted data, the orange curve represents the surveys where iterative reconstruction (IR) was used and the green curve represents the surveys where IR was not used. The present national DRL is represented by the vertical red line. The national DRL was derived from data submitted in earlier years and, consequently, the DRLs do not match the 75th percentile of the plotted distributions.
