[Contact microradiography of bone sections with various radiation properties]

A comparative evaluation of contact micrographs from microtome sections of nondecalcified bony tissue, exposed with bremsstrahlung (6 kv) and with titan-k-alpha radiation (6, 10 kv), filtered and unfiltered, was made on the basis of microphotograms. Only minimal differences in quality could be established which were of questionable significance. Optimal microradiographs therefore can be produced with Ti-k-alpha radiation. For practical purposes, the method is superior to other radiation qualities because of the short exposure time.
