Abstract

The linear and mass absorption coefficients of various leaves (fresh and dry) of Asoka plant studied by using beta sources Cs and Tl. Our study explores the validity of the expected exponential absorption law for leaves. The experimental and theoretical values are well agreement with the mixture rule. The linear and mass absorption coefficient values are useful for quantitative evaluation of interaction of radiations with leaves of plants.
