Description:
Grass ecosystem was monitored for ^1^3^7Cs, a relatively long-lived radionuclide, for about 16 years since the Chernobyl reactor accident occurred on April 26, 1986. Cesium-137 in grass gramineae or poaceae the species, ranged from 122.9Bqkg^-^1 (September 4, 1986) to 5.8mBqkg^-^1 (October 16, 2001) that is a range of five orders of magnitude. It was observed that there was a trend of decreasing ^1^3^7Cs with time reflecting a removal half-time of 40 months (3 1/3 years), which is the ecological half-life, T"e"c of ^1^3^7Cs in grassland.
