Characteristics of Ra-226 particles from legacy contamination and implications for radiological protection Open
Radioactive particles are physically discrete sources of radioactivity that have been released into the environment as result of past accidents, incidents, and practices, and can present a hazard to members of the public. The historical us…

Immune-modulatory effects of low dose γ-radiation on wax moth (<i>Galleria mellonella</i>) larvae Open
Larvae of the greater wax moth Galleria mellonella are common pests of beehives and commercial apiaries, and in more applied settings, these insects act as alternative in vivo bioassays to rodents for studying microbial virulence, antibiot…

Ecologically relevant radiation exposure triggers elevated metabolic rate and nectar consumption in bumblebees Open
Exposure to radiation is a natural part of our environment. Yet, due to nuclear accidents such as at Chernobyl, some organisms are exposed to significantly elevated dose rates. Our understanding of the effects of radiation in the environme…

Ensuring robust radiological risk assessment for wildlife: insights from the International Atomic Energy Agency EMRAS and MODARIA programmes Open
In response to changing international recommendations and national requirements, a number of assessment approaches, and associated tools and models, have been developed over the last circa 20 years to assess radiological risk to wildlife. …

Towards an ecological modelling approach for assessing ionizing radiation impact on wildlife populations Open
The emphasis of the international system of radiological protection of the environment is to protect populations of flora and fauna. Throughout the MODARIA programmes, the United Nations’ International Atomic Energy Agency (IAEA) has facil…

Chernobyl-level radiation exposure damages bumblebee reproduction: a laboratory experiment Open
The consequences for wildlife of living in radiologically contaminated environments are uncertain. Previous laboratory studies suggest insects are relatively radiation-resistant; however, some field studies from the Chernobyl Exclusion Zon…

Protection of the environment Open
The International Commission on Radiological Protection’s (ICRP) system to protect the living components of the environment is designed to provide a broad and practical framework across different exposure situations. The framework recognis…
View article: Radiation-mediated supply of genetic variation outweighs the effects of selection and drift in Chernobyl Daphnia populations
Radiation-mediated supply of genetic variation outweighs the effects of selection and drift in Chernobyl Daphnia populations Open
Populations experiencing varying levels of ionising radiation provide an excellent opportunity to study the fundamental drivers of evolution. Radiation can cause mutations, and thus supply genetic variation; it can also select against indi…

Cadmium uptake from sediment by <i>Cylindrotheca closterium</i> and the effect of diatom presence on partitioning of cadmium between sediment and water: A laboratory study Open
Although it is well established that microalgae take up metals and other contaminants from water and it has been suggested that algae may play a significant role in mobilizing sediment bound contaminants, there has been little research on …

Variation in chronic radiation exposure does not drive life history divergence among <i>Daphnia </i>populations across the Chernobyl Exclusion Zone Open
Ionizing radiation is a mutagen with known negative impacts on individual fitness. However, much less is known about how these individual fitness effects translate into population‐level variation in natural environments that have experienc…

Field effects studies in the Chernobyl Exclusion Zone: Lessons to be learnt Open
In the initial aftermath of the 1986 Chernobyl accident there were detrimental effects recorded on wildlife, including, mass mortality of pine trees close to the reactor, reduced pine seed production, reductions in soil invertebrate abunda…

Implementation of the integrated approach in different types of exposure scenarios Open
The International Commission on Radiological Protection (ICRP) recognises three types of exposure situations: planned, existing, and emergency. In all three situations, the release of radionuclides into the natural environment leads to exp…
