Measurements have been made to determine the levels of radioactivity in silt in the River Lea using the gross beta count rate method and γ-ray spectrometry. The results show that the environmental levels are very low and appear to be due to naturally occurring potassium, uranium and thorium and a small amount of 137Cs, probably from fallout. The evidence suggests that pollution due to radioactivity present in the river is negligible.
