Co-60 Attenuation Data

Cobalt-60 sealed sources are used throughout the industrial radiography industry to detect structural damage to metal parts. QSA Global’s Co-60 sealed sources are used to perform industrial gamma radiography with relatively short exposure time on thicker materials such as heavy castings, thick steel weldments, and concrete.

Material Material Density Half-Value Thickness
Concrete ~2.35 g/cm3 ~2.400 in (61.0 mm)
Steel ~7.80 g/cm3 ~0.827 in (21.0 mm)
Lead ~11.34 g/cm3 ~0.500 in (12.7 mm)
Tungsten ~17.80 g/cm3 ~0.310 in (7.9 mm)
Depleted Uranium (DU) ~18.70 g/cm3 ~0.270 in (6.8 mm)
