https://www.ancienttl.org/issue/feed Ancient TL 2025-02-06T09:12:58+00:00 Christoph Schmidt info@ancienttl.org Open Journal Systems <p>Ancient TL (electronic ISSN 2693-0935) is a community-based, not-for-profit, peer-reviewed, diamond open access journal with bi-annual issues in June and December. It is devoted to theoretical and experimental luminescence and electron spin resonance (ESR) research. This includes research on environmental dose rate, rock thermal histories (e.g., low-temperature thermochronometry) and mineral provenance and characterisation. Manuscripts on luminescence and ESR dating, on software codes, numerical models and on instrumentation are also welcome. Ancient TL also publishes interlaboratory comparisons, standardisation procedures, failed experiments, as well as observations difficult to explain. Following Ancient TL’s tradition, manuscripts about practical aspects of laboratory and field work are explicitly welcome.</p> <p>Periodically, Ancient TL publishes an up-to-date bibliography, thesis abstracts, and miscellaneous information for the community. Accepted articles are published immediately online (rolling publishing) before being included in one of the bi-annual issues.</p> https://www.ancienttl.org/article/view/6884 Editorial 2025-01-06T14:36:26+00:00 Christoph Schmidt christoph.schmidt@unil.ch 2025-01-11T00:00:00+00:00 Copyright (c) 2025 Christoph Schmidt https://www.ancienttl.org/article/view/6885 A new reference block for field gamma spectrometry applications in ESR and luminescence dating 2025-01-06T14:49:33+00:00 Mathieu Duval mathieu.duval@cenieh.es Miren del Val 123@unil.ch María Jesús Alonso Escarza 123@unil.ch Lee J.

Independent evaluations of the block’s gamma dose rate using passive Al<sub>2</sub>O<sub>3</sub>:C dosimeters and various field gamma spectrometer (NaI) probes produce consistent results of 1495 ± 51 μGy a<sup>-1 </sup>and 1514 ± 43 μGy a<sup>-1</sup> (or 1537 ± 19 μGy a<sup>-1</sup>, depending on the evaluation procedure employed), respectively. Bulk radioelement concentrations calculated from field gamma spectrometry using the Windows method are as follows: K = 1.58 ± 0.08 %, U = 4.26 ± 0.28 ppm, and Th = 12.62 ± 0.72 ppm. This new block complements existing dosimetry reference materials accessible at other laboratories and is available for the broader trapped charge dating community to use for instrument calibration, reproducibility assessments and intercomparison studies.</p> </div> </div> </div> 2025-01-11T00:00:00+00:00 Copyright (c) 2025 Mathieu Duval, Miren del Val, María Jesús Alonso Escarza, Lee J.
