title: Natural effective half-life of 137Cs in tea plants.
abstract: Contamination levels and variation of 137Cs in tea plant leaves from 1986-1992 were determined over the coast line of the Eastern Black Sea region in Turkey. The decrease of 137Cs radionuclide concentration in tea plant leaves may be described by a double exponential function with 94.8% activity lost with a Teff of 125 d and 5.2% activity lost with a Teff of 1,114 d.
