Arctic Ozone Hole and Enhanced Mid‐Latitude Ozone Losses Due To Heterogeneous Halogen Chemistry Following a Regional Nuclear Conflict

open access: yesEarth's Future, Volume 13, Issue 12, December 2025.
Abstract In a global‐scale nuclear war, massive explosions, intense heat, and radioactive fallout would cause extensive harm to humanity and ecosystems. Further, previous studies of even regional‐scale nuclear conflicts show that the smoke from large‐scale fires caused by such weapons could lead to global‐scale ozone loss.

Activities of \gamma-ray emitting isotopes in rainwater from Greater Sudbury, Canada following the Fukushima incident

open access: yes, 2012
We report the activity measured in rainwater samples collected in the Greater Sudbury area of eastern Canada on 3, 16, 20, and 26 April 2011. The samples were gamma-ray counted in a germanium detector and the isotopes 131I and 137Cs, produced by the ...

From “Modern Midas Mineral” to “Satanic Substance”: Uranium, Unions, and the Atomic Age

open access: yesAustralian Journal of Politics &History, Volume 71, Issue 4, Page 735-752, December 2025.
Uranium mining and export was a major flashpoint for political debate in 1970's Australia. However, there has been relatively little investigation into how uranium was understood and contested before this time. This paper draws on labour movement publications and other archival sources to reveal lesser‐known antecedents to the anti‐uranium movement in ...

Factors affecting the cesium transfer factor to shiitake (Lentinula edodes) cultivated in sawdust medium

open access: yesJournal of Wood Science, 2021
The transfer factor (TF) of radioactive cesium-137 (137Cs) to shiitake (Lentinula edodes) cultivated on bed logs varies greatly. Therefore, the present study investigated which factors affect the TF using stable cesium-133 (133Cs) and sawdust medium with

A continuous 500‐year sediment record of inundation by local and distant tsunamis in South‐Central Chile (40.1°S)

open access: yesThe Depositional Record, Volume 11, Issue 5, Page 1285-1310, November 2025.
Tsunami events over the past 500 years inundated Laguna Gemela West (Chile), leading to distinct sandy deposits in the lake record. This provides a complete perspective on tsunami inundation, including giant tsunamis, small local tsunamis and tsunamis that originated >100 km away from the site.

Trace americium contamination sources in the environment can be detected using 243Am/241Am

open access: yesCommunications Earth & Environment
Despite the widespread presence of americium in the environment since the 1950s from nuclear activities, the use of americium isotopic composition to trace contamination sources has not been investigated.

Actinides, accelerators and erosion

open access: yesEPJ Web of Conferences, 2012
Fallout isotopes can be used as artificial tracers of soil erosion and sediment accumulation. The most commonly used isotope to date has been 137Cs. Concentrations of 137Cs are, however, significantly lower in the Southern Hemisphere, and furthermore ...
