Abstract
Three kinds of common plant: bastard banian (Ficus retusa), hsianshih trees (Acacia confusa) and pine trees including their cones grown in s emitropical areas were investigated to serve as bio-indicators for Cs- 137 contamination in soil in Taiwan. Gamma spectroscopy was performed to measure the concentration of Cs-137 in soil and different parts of the plants. The results indicate that either the pendent rootlets of t he bastard banian or the pine tree including its cones can be used as bio-indicators for environmental radioactivity monitoring. Though the effectiveness of the hsianshih tree iis an indicator is known to be in ferior to others, its popularity makes it a potential bio-indicator in semitropical area.
