摘要: A continuous casting mold comprises a mold tube encased in a water jacket. A radioactive source on one side of the mold tube and scintillation crystal detector on the opposite side of the mold tube are employed to gauge the level of the molten metal in the tube. The amount of radioactive source material is maintained at an inherently safe level by disposing the source material in one or more recesses in the wall of the mold tube and by employment of a "gel" light tube connection between the scintillation crystal and a photomultiplier.
