Fig. 7

Strips of zinc that have been soldered together and subsequently rolled out to a uniform thickness. This image shows faint shadows where the soldering took place which shows that the difference in atomic number and density between the zinc and the soldering (consisting of tin and lead) is enough to show up on the radiographic image although the thickness is the same everywhere. Manually written legend: ‘Vier verlöthete und nachher ausgewalste Zinkstreifen” (four zinc strips soldered together and afterwards rolled out into one plate). Paragraph referral: § 14
