Radiation does response of calcium carbonate crystal in marine shells samples [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2002
A study of the evolution of element, crystal structure and thermoluminescence signal versus gamma irradiation dose were carried out for calcite shells samples. The composition of element was studied by X-ray fluorescence spectrometer.

Optically stimulated nanodosimeters with high storage capacity [PDF]

, 2019
In this work we report on the thermoluminescence (TL) and optically stimulated luminescence (OSL) properties of beta-Na(Gd,Lu)F-4:Tb3+ nanophosphors prepared via a standard high-temperature coprecipitation route. Irradiating this phosphor with X-rays not

Geochronology of the Whittlesey sedimentary succession, eastern England: The ‘Pompeii’ of the British late Middle Pleistocene to Holocene record

Journal of Quaternary Science, EarlyView.
Abstract The sedimentary succession at Whittlesey preserves a unique British late Middle Pleistocene to Holocene record back to a time equivalent to at least marine oxygen isotope stage 8 (ca. 250 ka). This study builds on previously published sedimentology, geochronology and palaeoecology results to establish 20 sedimentary facies associations, with ...

Thermoluminescence fading studies: Implications for long-duration space measurements in Low Earth Orbit

, 2013
Within a 1.5 year comprehensive fading experiment several batches of LiF:Mg,Ti and LiF:Mg,Cu,P thermoluminescence detectors (TLDs) were studied. The TLDs originated from two manufacturers and were processed by three laboratories using different annealing

One‐year follow‐up after fractionated ultra‐high‐dose‐rate FLASH radiotherapy in patient with extramammary Paget disease of the scrotum

Precision Radiation Oncology, EarlyView.
An elderly male patient with extramammary Paget disease of the scrotum and multiple metastases was treated with fractionated FLASH‐RT (40 Gy in 5 fractions) in the scrotal lesion. Abstract Objective Ultrahigh‐dose‐rate radiotherapy (FLASH‐RT) has been shown to reduce radiation‐induced normal tissue injury in preclinical studies.

Thermoluminescent aerosol analysis [PDF]

, 1977
A method for detecting and measuring trace amounts of aerosols when reacted with ozone in a gaseous environment was examined. A sample aerosol was exposed to a fixed ozone concentration for a fixed period of time, and a fluorescer was added to the ...

Luminescence dating and mineralogical investigations of bricks from erikli basilica in Stratonikeia ancient city (SW-Turkey) [PDF]

, 2017
Stratonikeia is one of the oldest settlements in southwestern Anatolia and at the same time significant for an understanding of the Hellenistic period. Archaeological records of Stratonikeia date back to around 2000 BC.

Breaking Concentration Quenching for Excellent Highly Efficient and Stable Narrowband Luminescence by Structural Ordering and Defect Regulation

Rare Metals, EarlyView.
ABSTRACT Enhancing the performance of phosphor materials for wide‐color‐gamut and high‐brightness phosphor‐converted light‐emitting diodes (pc‐LEDs) represents a critical materials challenge. Improving quantum efficiency (QE) under concentration quenching constraints and maintaining thermal stability remain primary objectives.
