Information on background Radiation is very useful in analyzing the effect of increase in radiation level after a nuclear accident. Under the Base Line Environmental Radiation Monitoring Program, Sri Lanka land area is divided into four hundred (400) squares and sampling the soil and grass is being carried out. The main objective of this program is gathering existing concentrations of natural and artificial radio-nuclides in near surface soil and plants.Currently sampling was completed at Three Hundred and fifty five (355) locations and GammaSpectroscopy Analysis was completed in 189 locations Including Soil and Grass samples.
