Abstract: To present a ceramic body the density of which is great, that is high strength, and that exhibits a superior radiation shielding effect, and a manufacturing method for this. A ceramic body in which by firing clay into which ferrite powder has been mixed at a proportion of 60 wt% after being formed into a specified shape, the density after firing has been made 3.5 g/cm 3 and the radiation shielding effect has been enhanced is obtained. For the ferrite powder, one that is expressed by the compositional formula: AO ・nX 2 O 3 (however, it should be noted that in said compositional formula, A is one type or more of an element selected from among Mg, Ca, Mn, Co, Ni, Cu, Sr, Ba, or Pb, X is one type or more of an element selected from among Fe, Co, or Ni, and n is a mol ratio that is defined as an integer from 1 to 9) is used.

Abstract: To present a molded body for structure construction such as a brick or a tile and the like and is a molded body for structure construction brick that is suitable for use for the construction of radiation shielding structures. A molded body for structure construction in which by firing clay into which ferrite powder has been mixed included at a proportion of 60 wt% after being formed into a specified shape, the density after firing has been made 3.5 g/cm 3 and the radiation shielding effect has been enhanced is obtained. It is preferable that press molding be carried out with the previously mentioned molding material and the compression strength of the molded body for structure construction made 100 MPa or greater. In addition, for the ferrite powder, it is preferable that one that is expressed by the compositional formula: AO ∙ nX2O 3 (however, it should be noted that in said compositional formula, A is one type or more of an element selected from among Mg, Ca, Mn, Co, Ni, Cu, Sr, Ba, or Pb, X is one type or more of an element selected from among Fe, Co, or Ni, and n is a mol ratio that is defined as an integer from 1 to 9) be used.
