摘要: Abstract We have carried out an investigation to test whether mini X-ray generators are a suitable alternative radioactive sources in luminescence dating. The study has mainly been motivated by the need for high dose rates (∼1 Gy / s ) make dating of older samples using regeneration protocols more practical. Furthermore, suited field work and countries where regulations restrict use sources. system tested here (a 50 kV 1 mA Varian VF-50J tube with tungsten target matched Spellman high-voltage power supply) was found provide: (i) excellent linearity between current (as set user on control computer) rate, (ii) wide dynamic range: 2– 30 mGy at 10 10– 2000 , (iii) short-term stability better than 0.2%, (iv) highly uniform irradiation sample area. Tests thermally sensitized sedimentary quartz suggest that we can beta interchangeably from point view construction growth curves single-aliquot regenerative-dose protocol.
