We hypothesised that the activity of radionuclides incorporated into trabecular bone will more accurately match the activity in the environment and the food chain at the time of death than the activity in cortical bone because of a higher remodelling rate.
The department houses low-background well-type gamma spectrometers for use in measuring the radioactivity of sediments and soils.
The facility has undertaken these analyses for research projects based in many areas of the world.
This approach can also be used in a number of other ways to investigate the distribution of radioisotopes in the environment through measurements of a wide range of environmental and ecological samples.
In legal medicine, the post mortem interval (PMI) of interest covers the last 50 years.
When only human skeletal remains are found, determining the PMI currently relies mostly on the experience of the forensic anthropologist, with few techniques available to help.
A dataset of historical sediment Carbon and Nitrogen isotope measurements from lake cores (n=95) spanning the range of lake types and catchments found across the UK. Nitrogen and Carbon isotope data from 210Pb dated lake sediment cores in the United Kingdom. https://doi.org/10.5285/4b53b1d7-f290-4b47-97e9-9f9ec79f3003 Lineage The Environmental Change Research Centre (ECRC), University College London core archive has been used to compile a UK wide, time slice dataset of lake sediment Nitrogen and Carbon and stable isotope measurements.
These data have been obtained from the Environmental Change Research Centre (ECRC) lake sediment core archive with well-resolved time intervals (1850, 1900, 1980 and present) determined by radiometric dating (210Pb; 137Cs). The sediment archive has grown from lake coring projects undertaken by the department and employees of ENSIS Ltd, the environmental consultancy based within the ECRC.
This enables sediment chronologies over the last 100–150 years to be accurately determined.At L’adové pleso, multiple cores were collected in order to establish spatial distribution of sediments over the bed of the lake.Cores from all sites had good records of the fallout radionuclides from which it was possible to construct reliable chronologies of the recent sediments.UK Environmental Change Research Centre, University College London ( Before sending samples for analysis it is important to contact either Handong Yang or Neil Rose (see Contacts) regarding up-to-date costs and the time from receipt of samples to reporting as this can vary depending on demand.
