A detailed gamma ray survey in 1994 and newly calculated beta attenuation data led to total dose rate estimations that are between 0 and 30% smaller than previously estimated. Accordingly, the resulting ESR age estimates are between 0 and 30% older. The ESR dates are now in good agreement with independent age estimates, particularly 14C and amino acid racemization. New ESR dates for the lowermost dated sedimentary layers, 5 WA (white ash), indicate that the sedimentation of the sequence started around 200 ka ago.Keywords: archaeological evidence; dating method; electron spin resonance dating; sedimentation; animal; article; chemistry; electron spin resonance; enamel; fossil; hominid; human; methodology; regression analysis; sediment; Animals; Dental Enamel; Electron Spin R BC1 to BC8; Border cave; ESR dating; Howieson's poort; LSA; MSA200110.1006/jhev.2001.04712015-12-10
