Assessment of dose due to exposure to indoor radon and thoron progeny [PDF]

open access: yesNuclear Technology and Radiation Protection, 2010
The components of the effective dose through inhalation from radon and its progeny are important for human health since they contribute to more than 50% of the total radiation dose from natural sources.

Top‐Down Versus Bottom‐Up Atmospheric Emission Estimates From Oil and Natural Gas Operations

open access: yesEarth's Future, Volume 13, Issue 11, November 2025.
Abstract This study reviews results from literature to investigate top‐down versus bottom‐up emission estimates from oil and natural gas (O&NG) operations. Ten years ago, a landmark study by Brandt et al. (2014, https://doi.org/10.1126/science.1247045) found generally higher top‐down emissions determinations than industry estimates.

Shallower Living Depth Instead of Higher Seawater Alkalinity Enhanced Calcification in Bloom‐Forming Coccolithophores During Their Pleistocene Acme Event

open access: yesAGU Advances, Volume 6, Issue 5, October 2025.
Abstract Coccolithophores are a group of marine phytoplankton precipitating about 50% of total calcite carbonate in the surface ocean. During the Pleistocene, coccolithophores experienced several periodic high‐abundance and dominance intervals (acmes) that significantly altered the ocean carbon cycle by increasing the production of carbonate in the ...

Gradual Warming of Western Pacific Warm Pool Due To Weakening of Indonesian Throughflow During the Late Mid‐Pleistocene Transition

open access: yesGeophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract The nature and cause(s) of the Mid‐Pleistocene Transition (MPT) remain enigmatic. Notably, the role of tropical Pacific oceanographic changes during the late MPT (∼0.9–0.6 Ma) remains understudied. Here, we generated ∼1.4‐Myr‐long Mg/Ca and δ18O records for the planktonic foraminifer Trilobatus sacculifer from IODP Site U1490 to reconstruct ...

Contrasting Trends in Phytoplankton Diversity, Size Structure, and Carbon Burial Efficiency in the Mediterranean Sea Under Shifting Environmental Conditions

open access: yesJournal of Geophysical Research: Oceans, Volume 130, Issue 8, August 2025.
Abstract Shifts in the phytoplankton assemblage induced by environmental changes have significant implications for carbon cycling and marine food webs, but remain poorly constrained across spatiotemporal scales. Here, we investigate the effects of rising sea surface temperatures and increased stratification on the phytoplankton composition and size in ...

Study on influence of soil and atmospheric parameters on radon/thoron exhalation rate in the Bangalore University campus, Bengaluru

open access: yesRadiation Protection and Environment, 2018
In the present study, Radon (222Rn) and Thoron (220Rn) concentration have been measured in the Bangalore University Campus using RAD7 during the postmonsoon season. The results reveal that 222Rn concentration ranged from 360 ± 146 to 643 ± 196 Bq/m3 with
