This study provides methodological aspects on the equivalent dose estimation for travertine samples, namely heated calcium carbonate, using the TL multiple-aliquot additive-dose approach. Large equivalent doses (EDs), within the range 750–1300 Gy, were calculated using the plateau method based on the NTL glow curve. Moreover, a component resolved TL glow-peak analysis was carried out, using the integrated intensity of the NTL glow peaks for the ED estimation after deconvolution based on the OTOR model. Three different TL peaks were used, termed P4, P5 and P6. The integrated intensity of TL glow peak P4 resulted in age overestimation (15–26%), compared to the age provided using the plateau method. This overestimation could be attributed to the fact that the temperature range of P4 does not coincide with the plateau region of each sample. Milder overestimation (8–14%) was noticed using the integrated intensity of TL glow peak P6, mostly due to the poor deconvolution resolution. Only the integrated intensity of TL glow peak P5 after deconvolution provides ED values compatible with those yielded using the plateau method, with good accuracy. The present study suggests not using the TL intensity (neither in terms of integrated intensity nor of peak height intensity) for ED estimation; instead it is highly recommended to use either the plateau method, or alternatively integrated intensity of TL peak P5 after deconvolution. Unfortunately, using the peak height of TL P5 is not recommended, due to overlapping with P6.

使用来自土耳其安那托利亚的石灰华样品的TL辉光曲线估算组分分辨的等效剂量

这项研究提供了使用TL多等分加样剂量法估算石灰华样品(即加热的碳酸钙)的等效剂量的方法论方面。使用基于NTL辉光曲线的平稳方法计算了750-1300 Gy范围内的大当量剂量(ED)。此外,基于NTR辉光峰的积分强度,基于OTOR模型进行反卷积后的ED估计,进行了成分分解的TL辉光峰分析。使用了三个不同的TL峰,称为P4,P5和P6。与使用高原法提供的年龄相比,TL辉光峰P4的综合强度导致年龄高估(15–26%)。这种高估可能归因于P4的温度范围与每个样品的平稳区域不一致。使用TL辉光峰P6的积分强度,发现温和的高估(8–14%),主要是由于反卷积分辨率差。去卷积后,只有TL辉光峰P5的积分强度才能以良好的精度提供与使用平稳方法产生的ED值兼容的ED值。本研究建议不使用TL强度(无论是在积分强度方面还是在峰高强度方面)进行ED估计;相反,强烈建议使用平稳方法,或者在解卷积之后使用TL峰P5的积分强度。不幸的是,由于与P6重叠,不建议使用TL P5的峰高。去卷积之后,只有TL辉光峰P5的积分强度才能以良好的精度提供与使用平稳方法产生的ED值兼容的ED值。本研究建议不要将TL强度(既不是积分强度也不是峰高强度)用于ED估计。相反,强烈建议使用平稳方法,或者在解卷积之后使用TL峰P5的积分强度。不幸的是,由于与P6重叠,不建议使用TL P5的峰高。去卷积之后,只有TL辉光峰P5的积分强度才能以良好的精度提供与使用平稳方法产生的ED值兼容的ED值。本研究建议不使用TL强度(无论是在积分强度方面还是在峰高强度方面)进行ED估计;相反,强烈建议使用平稳方法,或者在解卷积之后使用TL峰P5的积分强度。不幸的是,由于与P6重叠,不建议使用TL P5的峰高。相反,强烈建议使用平稳方法,或者在解卷积之后使用TL峰P5的积分强度。不幸的是,由于与P6重叠,不建议使用TL P5的峰高。相反,强烈建议使用平稳方法,或者在解卷积之后使用TL峰P5的积分强度。不幸的是,由于与P6重叠,不建议使用TL P5的峰高。
