“…Further to this, additional external beta dose attenuation calculations using One Group Theory (O'Brien et al, 1964) which we have extended to include all the isotopes in the U and Th decay chains and radioactive potassium, support the results obtained using Monte Carlo methods. Further experimental data combined with the theoretical calculations will be reported elsewhere (see note added in proof).…”

“…This method is based on one-group theory (O'Brien et al, 1964;Prestwich et al, 1997), which has been shown to be in close agreement with experimental measurements and recent Monte Carlo calcu- lations of beta attenuation in tooth enamel (Brennan et al, 1997;Yang, 1997;Yang et al, 1998). These calculations are incorporated into a new software package called ROSY (Brennan et al, 1999), which is available from the McMaster University ESR dating group.…”

Electron spin resonance (ESR) and thermal ionization mass spectrometric (TIMS) ²³⁰Th/²³⁴U dating of teeth in Middle Paleolithic layers at Amud Cave, Israel

Electron spin resonance (ESR) dating and thermal ionization mass spectrometric 230 Th/ 234 U dating was conducted on six teeth from the prehistoric site of Amud Cave. By combining the ESR and 230 Th/ 234 U analyses, we obtained burial ages for teeth in various layers of the site. Layer B 1 /6-7, from which the Amud I Neanderthal skeleton was recovered, is dated to 53 Ϯ 8 ka. Layer B 2 /8, which yielded other important human remains including the Amud 7 skeleton, gives a mean burial age of 61 Ϯ 9 ka. One tooth from the lowest layer (B 4 ) yielded a date of 70 Ϯ 11 ka, but another tooth from this layer gave an 113 Ϯ 18 ka. Despite this discrepancy, these ages agree with previously published TL ages on heated flints for the corresponding layers. This agreement between ESR on tooth enamel and TL on burned flint is also seen at all other sites studied with both methods in Israel. ᭧
