The upper left shows the image under a microscope, and the upper right shows the
microradiograph. [sup.137]Cs concentration was not high in the newly developing tissue itself (i.e., plumule and radicle) but was higher in the surrounding tissue.
Care was necessary to keep the sample exactly perpendicular to the wheel so that no bevel could form and cause a false mineral density gradient in the x-ray
microradiograph. The exposed enamel edge was rubbed with acetone to be sure that no cured epoxy might have been smeared across the enamel surface during the polishing process (Fig.
After 5 days a radiolucent line along with the incremental line was seen in
microradiographs indicating enamel formation was influenced by high fever.
Microradiographs were performed on KODAK professional Industrex SR45 film (100NIF) on a faxitron X-ray System (Hewlett-Packard, San Diego, Calif., USA).
The cut section photographs and
microradiographs were scanned into a computer.
