Summary
A method of estimating water in a neutron image was developed for cold neutron radiography, where the scanning method was applied to the plant sample at a beam port. The spectrum of the cold neutron beam as well as the effective cross section of water was determined to estimate the water thickness in chrysanthemum tissues. The resolution and contrast of the cold neutron radiography were sufficient for the estimation of the water thickness of fine veins in the chrysanthemum leaves. However, volumetric water content was overestimated when the sample shapes were cylindrical. This phenomenon can be explained by the reduction of the effect of neutron scattering from the sample when it is cylindrical.
