Land Soil

A land soil sampling plan has been set up to monitor the long-term variation in the concentration of artificial radionuclides in soil. Sampling from the 39 designated sites throughout the territory is spread over a cycle of six years. At each site, samples are collected from two layers, the upper layer from the surface to 15 cm deep and the lower layer from 15 to 30 cm deep. Measurements of the radioactivity of these samples are carried out at the Radiation Laboratory at King's Park.
