This research aimed to measure radon activity concentrations in bottled drinking water (BDW) samples consumed in Kahramanmaraş town, Turkiye. Also, to evaluate the health risk that may occur as a result of internal irradiation resulting from ingestion and inhalation of radon in BDW samples, the total annual effective dose equivalent (AEDE) for infants, children, and adults (1-2 y, 2-12 y, and > 17 y) and excess lifetime cancer risk (ELCR) for adults (> 17 y) had to be calculated. For these purposes, 32 water samples of different volumes belonging to 8 different commercial brands, representing a large part of the BDW consumed as drinking water and sold commercially in Kahramanmaraş were collected by purchasing from markets.

In this paper we present the high-precision and accurate Th/Th isotope ratio measurement by a novel multi-collector inductively coupled plasma mass spectrometer with a pre-cell mass filter and a MS/MS collision/reaction cell (Neoma™ MC-ICP-MS/MS). No tailing correction is needed for the Th signal, as the tailing of an adjacent high intensity peak (abundance sensitivity) is effectively reduced due to high extent of Ar-based ion removal before the electrostatic analyser/magnetic sector. The obtained abundance sensitivity at m-2 (i.

Etizolam, a type of anxiolytic drug, is the most commonly abused drug among hypnotic/anxiolytic medications in Japan. Although there have been reports on the postmortem identification of etizolam in the blood, the detailed distribution of etizolam among organs in an abuse case has not been reported. In this study, we examined etizolam concentrations in the blood and organs obtained from etizolam-related autopsy cases using the surrogate analyte approach (SAA) method, which can be analytically used without blank samples.

The phenomenological and microscopic level density models were utilized within the TALYS 2.0 software to simulate the cross-sections of proton-induced reactions on both natural and enriched copper. This process resulted in the production of the zinc radioisotopes Zn, Zn, and Zn, which hold significance in diagnostic and therapeutic medicine.

Quantitatively assessing the origins of aerosol zinc (Zn) is crucial for understanding of the global atmospheric Zn cycle and for formulating targeted policies to mitigate anthropogenic Zn emissions. Zn isotope ratios (denoted as δ⁶⁶Zn) serve as powerful tools for constraining the origins of aerosol Zn. This review comprehensively compiles an δ⁶⁶Zn (relative to Lyon JMC Zn standard) dataset (n = 207) for multi-sized aerosols observed exclusively in the Northern Hemisphere, encompassing diverse atmospheric environments, including urban areas and remote deserts, glacier, and ocean.
