The radioactive cobalt-60 material sits in a double encapsulated 304 or
304L stainless steel capsule which is 0.375 inches wide by 0.938 inches
long. This small capsule is stored in a depleted uranium shield which is
made in two pieces. These pieces are secured within the outer shell with a
bolt flange and carbon steel positioning angle supports and circumference
rings. The depleted uranium shielding is housed in a 300 series stainless
steel welded outer shell. The stainless steel outer shell is comprised of
a 12 3/4 inch diameter by 16 inch tall right circular cylinder. This
device is equipped with a lock-knob, designed to lock the source in its
normally stored position, for safe transportation.
