Radionuclides in the environment require regular monitoring to establish activity concentrations and make reliable dose estimates. This study examines the variability in selected radionuclide activity concentrations at a variety of spatial scales and

The rapid and accurate quantification of radioactivity in the ground is important in many instances to enable appropriate decisions to be made about limiting its use. In-situ gamma spectrometry has been shown to be a potentially powerful technique fo

This paper presents a review of research into the occurrence and behaviour of neptunium, principally 237 Np, in the Irish Sea. This research has lagged behind that of other radionuclides due to the combination of 1. the relative difficulties in the a

In-situ gamma spectrometry is a potentially powerful method for rapid quantification of radioactive contamination in the ground using an above-ground detector. The accuracy of the technique, however, depends on having information on the activity vari

Long-lived radionuclides,99Tc,137Cs,237Np, Pu isotopes and241Am were determined in the long sediment cores collected from nine intertidal sites around the west Cumbria of the Irish Sea, UK. The inventories of all nuclides measured varied considerably

In situ gamma-ray spectrometry offers a rapid method of assessing radioactive contamination in soil. For accurate quantification, however, a knowledge of the activity - depth distribution is essential. Three methods, the multiple peak method, the pea

The Ribble Estuary in the UK is contaminated by radionuclides derived from BNFL Sellafield and Springfield. Following the temporary shutdown of the Springfields plant, beta dose and gamma air kerma rates were measured at a range of sites in the estua

Surface sediment samples were collected from the estuary of the River Ribble, UK, which is contaminated by radionuclides derived from BNFL Sellafield and Springfields. Activity concentrations were measured by gamma and alpha-spectrometry for 137 Cs,

The mean background beta dose and gamma kerma rates measured in the Ribble Estuary were 0.16 ± 0.14 μSvh −1 and 64 ± 8.5 nGyh −1 , respectively. Maximum total dose rates arising from radionuclides discharged from BNFL Sellafield and Springfiel
