Cast iron is an iron alloy containing 2 wt.% – 4 wt.% carbon, 1 wt.% – 3 wt.% silicon and smaller amounts of minor elements [1]. In comparison, steel has a lower carbon content of up to 2 wt.% and a lower silicon content. Cast iron can also be further optimized by alloying with small quantities of manganese, molybdenum, cerium, nickel, copper, vanadium and titanium before …

The marrow transit time of radioiron indicates the time required for the process of iron incorporation and red cell maturation. 18. Studies of this type indicate that in certain anemias—such as thalassemia, pernicious anemia and some "refractory" anemias with cellular marrow— the iron uptake by the marrow far exceeds the production of viable red cells. 19 …
