the studies also showed : 1 241am is initially deposited onto all types of bone surface including endosteal surfaces , periosteal surfaces and those of the vascular canals within cortical bone , but seems to be preferentially deposited onto those that are resorbing , 2 bone accretion results in the burial of surface deposits of 241am , 3 bone resorption causes the removal of 241am from surfaces , 4 resorbed 241am is retained by phagocytic cells ( probably macrophages ) in the bone marrow , 5 the transfer of 241am from the phagocytic cells in the marrow to adjacent bone surfaces seems to occur , ( local recycling ) .
