Paleoceanography and Paleoclimatology, Volume 40, Issue 6, June 2025.Abstract Assessing the preservation state of calcium carbonate microfossils preserved in deep‐sea sediments allows us to understand the impact of ocean chemistry on deep‐sea carbonate distribution and provides key information on potential biases affecting microfossil‐based proxies applied in the geological past.

Monitoring of 220Rn Concentrations in Buildings of Kufa Technical Institute, Iraq
Science and Technology of Nuclear Installations, 2015 This paper presents the measurements of thoron and the progeny in fifteen buildings in Kufa Technical Institute, Iraq, from June 2015 to April 2015 using RAD-7 detectors. Also, annual effective dose rate was calculated in all buildings under study.

CvdN Equilibrium and Share Equilibrium in Local Public Good Economies
Journal of Public Economic Theory, Volume 27, Issue 2, April 2025.ABSTRACT CvdN equilibrium and share equilibrium are both extensions of the cost‐shares‐based ratio equilibrium for global public good economies to local public good economies. CvdN equilibrium and share equilibrium differ in terms of the stability requirements for equilibrium jurisdictions.

Radiation Protection and Environment, 2018 The major contribution of natural background radiation exposure comes from radon, thoron, and their progeny. The activity concentration of these radionuclides depends on various factors, and the concentration level varies from place to place.

Indoor Air, Volume 2025, Issue 1, 2025.Exposure to radon‐222 (222Rn) and its decay products poses a significant public health risk. 222Rn tends to accumulate in poorly ventilated areas, underground spaces, and caves, which justifies the existence of international reference levels for its annual average indoor concentrations.

Exploring Seasonal Variation of Indoor Radon in Campania: Preliminary Findings
Indoor Air, Volume 2025, Issue 1, 2025.This study focuses on the indoor radon gas monitoring in 30 residences in Campania to evaluate seasonal variability. Approximately 570 CR‐39 solid‐state detectors were employed. Measurements were taken monthly, quarterly, semiannually, and annually, starting in October 2022 and ending in September 2023.

Outdoor radon and thoron in an area with naturally ventilating bedrock fractures
Frontiers in Environmental ScienceOpen fractures lead to increased permeability of the bedrock, and, if connected to the surface, allow for groundwater flow and air ventilation. Radon and thoron received by groundwater and ventilating air from bedrock can then be released at the surface.

Relationship of the 1979 Southern California Radon Anomaly to a possible regional strain event [PDF]
, 1981 During the second half of 1979, anomalously high emanation of radon was recorded at two stations of the automated radon-thoron monitoring network operated by the W. K. Kellogg Radiation Laboratory of the California Institute of Technology.
