Table 4. Radiosensitivity enhancement factor (REF) and dose reduction.

Cell type Radiation REF Dose reduction (%)
Huh7 γ-ray 1.41 29.2
Neutron 1.80 44.3
HepG2 γ-ray 1.16 13.8
Neutron 1.35 25.9

Values were obtained from Figure 2A.

REF: ratio of the radiation dose required to kill 90% of cells in the presence of gold nanoparticles divided by the dose in the absence of gold nanoparticles.
