     Some isotopes that are not alpha-emitters are also "bone[-]seekers," and are not well eliminated. The result is that even a small quantity of these materials, retained in the body, may lead to depression of bone marrow activity, and to serious bone lesions.

Kornberg, “Biological Implications of Radioactive Wastes”, inSixth International Congress and Exhibition of Electronics and Atomic Energy, Rome, Italy, June 1959: U.S. Papers (United States Atomic Energy Commission Technical Information Service;TID-7579), Oak Ridge, Tenn.: Division of International Affairs,United States Atomic Energy Commission,→OCLC,page 6:

     The bases of working limits for environmental contamination are the permissible limits for internal emitters. If the internal emitter is abone-seeker (examples are plutonium, Sr⁹⁰, and the rare earths) the criterion for establishing limits is based on the history of humans who have had radium deposited in their skeletons. To experimentally find the maximum quantity of a radioactivebone-seeker that can deposit in the human skeleton without adverse effect, it is usual to compare the toxicity in experimental animals of thebone-seeker with that of radium.

Kenneth Poggenburg, Jr., Alan Solomon, “The Use of Rare-earth Radionuclides and Other Bone-seekers in the Evaluation of Bone Lesions in Patients with Multiple Myeloma or Solitary Plasmacytoma”, inRadiology, volume125, number 1, Easton, Pa.:Radiological Society of North America,→DOI,→ISSN,→OCLC,→PMID, abstract, page171:

     In general, localization of the rare-earth "bone-seekers" was poor except for¹⁵⁷Dy, which compared well with^99mTc-PP and^99mTc-DP;¹⁵⁷Dy was also helpful in studies of the abdomen and pelvis because of its failure to concentrate in the gastrointestinal tract.

Priest, editor,Metals in Bone: Proceedings of a EULEP Symposium on the Deposition, Retention and Effects of Radioactive and Stable Metals in Bone and Bone Marrow Tissues, October 11th–13th 1984, Angers, France, Lancaster, Hingham, Mass.: MTP Press for the Commission for theEuropean Communities,→DOI,→ISBN,page59:

     These studies demonstrated that beside radionuclide retention anatomical and physiological factors affect the induction of radiation damage from incorporating α-emittingbone seekers to bone marrow.

     "The guy that just left—what's he got in his lungs?" / "Well, I'm not very sure. But the two best candidates are uranium-233 and plutonium-239, one or both." / "They're in his bones too, aren't they?" / "Yeah, they're bothboneseekers. And they've got half-lives of one hundred sixty-two thousand and twenty-four thousand years respectively. So they stay hot for a long time."

     Lead is abone seeker; it is found in bone mineral with a 70% higher level in cancellous bone than in compact bone.

Rostek, editors,Bi-annual Report 1992–1993: Operational and Research Activities of Central Laboratory for Radiological Protection‎^[1], Warsaw: Central Laboratory for Radiological Protection,→ISBN,→OCLC, archived fromthe original on14 February 2020,page74:

     [I]n general, inland waters exhibit much (2–3 orders of magnitude) higher concentrations of²²²Rn than of²²⁶Ra. This fact has, however, only very little meaning from the point of view of radiological protection, because²²⁶Ra being a long-lived, alpha-activeboneseeker, belongs to highly radiotoxic substances, whereas²²²Rn, a short-lived noble gas, does not.
