Technetium

The radionuclide Tc has been successfully measured with DGT using a specialist binding layer known as TEVA. DGT passive samplers equipped with this binding layer are available.

For deployments in all types of waters you will need device LSNV-NP

For deployment in soilsA you will need device LSLV-NP

For deployments in sedimentsB you will need LSPV-NP

Detailed instructions for the use of most DGT passive samplers are available.

AThese soil devices are designed for deployment in homogenised hydrated soil samples.

BThe sediment probes can be inserted directly into sediment and have a large enough area (exposure window 150 x 18 mm) to be capable of providing spatial information, e.g. vertical profiles or 2-D images. They have also been used to obtain similar information in hydrated soils (e.g. Luo et al., 2013).
