Natural VSL intensities from the Luochuan site exhibit growth up to ~1800 Gy.
The natural and single aliquot regenerated (SAR) dose-response curves do not overlap.
SAR induces incorrigible changes in trapping sensitivity and VSL decay curve shape.
VSL chronology in agreement with independent age control up to ~600 ka using a Multiple-Aliquot Additive-Dose (MAAD) protocol.
