FIRST THOMAS S. TENFORDE TOPICAL LECTURE: The Ethics of Radiological Protection.

abstract：:This paper examines in humans the proposition emanating from studies in beagles that initial retention of radium varies in proportion to the calcium addition rate at the time of intake. Human calcium addition rates were scaled from those in beagles, the relative calcium accretion rates in the two species at equivalent...
