Data collected as part of the NERC funded Radioactivity and the Environment (RATE), Long-lived Radionuclides in the Surface Environment (Lo-RISE), research consortium.This data comes from the marine workstream group based at the Scottish Universities Environmental Research Centre (SUERC) and the Scottish Association for Marine Science (SAMS). The data consists of radionuclide measurements of environmental and biological samples including radiocarbon, caesium (137), americium (241) and plutonium (238, 239, 240).The data has been published in the following publications: Tierney et al., 2018. Modelling Marine Trophic Transfer of Radiocarbon (14C) from a Nuclear Facility. Ecosystem Modelling and Software 102, 138-154. Tierney et al., 2017.

Trace metal mobilisation data (pH, ALK, Na, K, Ca, Mg, Li, SO4, Si, Be, Mn, Fe, Zn, Cu, Al,Sr, Be, Ba, Y,Co, Ni, B, Rb, Y, Cd, Sb, Cs, Ba, La, Ce, Nd, Pb, Th, U) for the River Carnon, the River Fal (downstream) and its estuary in Cornwall following discharge of highly polluted water from the Wheal Jane mine. In January 1992, there was a major pollution incident involving highly acidic wastes. CEH, in conjunction with the University of Reading monitored the River Carnon between September 1992 and April 1994, to examine the water quality.
