ICRP phantom was utilized to represent the medical personnel whereas MIRD phantom was used to represent the patient on the tabletop. Dose received by medical personnel were recorded at anterior posterior (AP) exposure projection at 73 kVp and 350 mAs for all the rooms. </span></span></span><span lang="en-US" style="font-size:9.0pt"><span style="font-family:Calibri"><span style="color:#1f497d"><span style="font-style:italic"><span style="font-weight:bold"><span style="language:en-US">Results: </span></span></span></span></span></span><span lang="en-US" style="font-size:9.0pt"><span style="font-family:Calibri"><span style="language:en-US">The study revealed variations in the equivalent doses received by medical personnel across different room configurations.
