For fields especially resistant to new ideas, Egyptology takes the prize. Thus far surface luminescence has been used only once, and produced results only just barely acceptable. A chip from a facing stone of one of the Giza pyramids, and from the Valley Temple showed an age of 5000 years, +/- 500 years, where the officially assumed age is 4500 years. That was enough of that! |

> Surface luminescence dating to Egyptian monuments of the age range 3000 B C to Hellenistic times has been applied for first time. Monuments include the Giza plateau (Sphinx Temple, Valley Temple, Mykerinus), the Qasr-el-Saqha, the Khasekemui tomb and the Seti I Temple with Osirion at Abydos. Equivalent doses were measured by the single and multiple aliquot additive and regeneration techniques, and dose rates by portable gamma ray probes, and with laboratory counting and dosimetry systems. The resulted ages have confirmed most conventional Dynastic dates, while in some cases, predating was obtained by some hundred of years. The dates are discussed in the light of current archaeological opinions.
From the conclusion:
> Different calculated and archaeological ages, beyond one standard error, were noticed for one sample at Valley Temple at Chephren's complex (limestone), one at Sphinx Temple (granitic), and one at Seti II Abydos (sandstone).
