In plain language
Measured scatter around computed tomography (CT) scanners can be estimated from the dose-length product (0.36 for body, 0.14 for head scans, µGy per mGy cm at 1 m), helping plan shielding and assess dose to staff present during CT fluoroscopy.

What it found
Recommended scatter factors to estimate scatter air kerma at 1 m from the CT isocentre differ for body and head scans.
Key figures: 0.36 µGy (mGy cm)(-1) body; 0.14 µGy (mGy cm)(-1) head
CT gantries transmit only a small fraction of scatter, which can be accounted for in shielding design.
Key figures: 10%
The factors can support risk assessments for staff who must be present during CT fluoroscopy procedures.
Limits to keep in mind
Abstract only; number of scanners and measurement conditions not stated, and results are physical measurements of scatter rather than staff doses or health outcomes.
