TREE was one of three consortia funded by the Natural Environment Research Council (NERC), the Environment Agency (EA) and Radioactive Waste Management Limited (RWM) under the Radioactivity And The Environment (RATE) programme.
The objective of the TREE project was to reduce uncertainty in estimating the risk to humans and wildlife associated with exposure to radioactivity and to reduce unnecessary conservatism in risk calculations through interlinked science components: improving understanding of the biogeochemical behaviour of radionuclides in soils, transgenerational effects of ionising radiation exposure on wildlife.
Studies combined controlled laboratory experiments with fieldwork - most of which took place in the Chernobyl Exclusion Zone (CEZ), Ukraine.
TREE data that is published and available for download:
* A 'Reference Site' in the Chernobyl Exclusion Zone: radionuclide and stable element data, and estimated dose rates
* Elemental and radionuclide concentrations for several vegetation species from a site in Extremadura, Spain
* Elemental concentrations in representative species of the ICRP's Reference Animals and Plants and associated soils in terrestrial Mediterranean ecosystems in Spain
* Radionuclide data for vertebrates in the Chernobyl Exclusion Zone
* Spatial datasets of radionuclide contamination in the Ukrainian Chernobyl Exclusion Zone
* Data for lead (Pb) in terrestrial wildlife and resultant taxonomic models
* Bird Vocalisation Activity (BiVA) database: annotated soundscapes from the Chernobyl Exclusion Zone
* Water chemistry of seven lakes in Belarus and Ukraine 2014 to 2016
* Impact of environmental radiation on the health and reproductive status of fish from Chernobyl, Ukraine 2014 to 2015
TREE data has been deposited with the EIDC but is under embargo; data will be published and available for download at end of embargo period:
* Effects of low-dose ionising radiation on reproduction and DNA damage in marine and freshwater amphipod crustaceans (embargoed until 19 July 2020)
* Impacts of chronic radiation exposure on reproduction, development and genetic diversity of the freshwater crustacean Asellus aquaticus at Chernobyl (embargoed until 20 August 2020)
* Impact of environmental radiation on the health and reproductive status of fish from Japan, 2017 (embargoed until 31 December 2020)
