Dose calculations use a 65 kg “TissueSoft” rectangular phantom (178 cm × 23 cm × 15 cm). Dimensions were chosen to mirror my own body.
Full-body dose assumes an air distance of 1480 mm due to tube FOV. The simulator accounts for tube FOV and distance to determine exposed phantom area (phantom facing tube).
Backscatter is not accounted for. With air or a high-Z surface behind the phantom, backscatter dose is negligible.
Health impact of localized high doses depends on many factors not modeled here. Acute radiation syndrome symptoms typically begin around a full-body dose of ~1 Gy recieved within a day—orders of magnitude above what this 160 keV setup can deliver under continuous operation.
