Radiographs Series 2

The second set of radiographs! Now with 8x10s, a multitude of items, lead markers, and somewhat improved techniques thanks in large part to Kenneth Low's Metallurgical and Industrial Radiography (1940, London) as well as Bray and Stanley's Nondestructive Evaluation (1989, New York). Improvements in exposure technique were also had, although primarily through practice. Intensification screens and true X-ray film (instead of print paper) to come soon...
