Figure 5 - Applied microradiography: (a) a solder joint in a small copper heat exchanger indicating excessive porosity in real time microradiography with 36x magnification; (b) a computer chip with microjoint wires (each individual wire is 25 µm [9.8 x 10-4 in.] in diameter).
Figure 6 - Real time microradiograph of a US dime with 4x magnification taken with a 5 µm (2 x 10-4 in.) focal size microfocus.
Figure 7 - Film microradiograph of fine shells: (a) with 16x magnification; (b) optically magnified. The shells were taken from samples of mud under a lake to study its geological history.
