Kanda and colleagues found that high signal in the brain's dentate nucleus and globus pallidus on unenhanced T1-weighted MRI correlated with the number of earlier gadolinium-based contrast doses.
As reported in: Kanda, Ishii, Kawaguchi et al. (2014). High Signal Intensity in the Dentate Nucleus and Globus Pallidus on Unenhanced T1-weighted MR Images: Relationship with Increasing Cumulative Dose of a Gadolinium-based Contrast Material. Radiology. doi:10.1148/radiol.13131669
Jensen and colleagues found rat adrenal (PC12) cells can take up plutonium through the iron-transport protein transferrin, but only when plutonium is bound in transferrin's C-lobe and iron in its N-lobe.

Chasteen and colleagues reviewed tellurium biology: unlike selenium it has not been found to be an essential trace element, and its soluble oxyanions tellurite and tellurate are toxic to most forms of life even at very low concentrations.
As reported in: Chasteen, Fuentes, Tantaleán et al. (2009). Tellurite: history, oxidative stress, and molecular mechanisms of resistance. FEMS Microbiology Reviews. doi:10.1111/j.1574-6976.2009.00177.x
After the 2006 death of Alexander Litvinenko, Harrison, Leggett and Lloyd evaluated human and animal data and dose models for ingested polonium-210 and concluded bone marrow failure is likely an important part of fatal damage.

Pooling 13 European case-control studies with 7,148 lung cancer cases, Darby and colleagues found lung cancer risk rose 16% per 100 Bq/m3 of usual home radon, with no evidence of a threshold.

Saltini and colleagues found that in chronic beryllium disease, beryllium acts as an antigen that makes beryllium-specific CD4+ helper T cells multiply and build up in the lungs, so the disease is a hypersensitivity reaction to beryllium.
As reported in: Saltini, Winestock, Kirby et al. (1989). Maintenance of Alveolitis in Patients with Chronic Beryllium Disease by Beryllium-Specific Helper T Cells. New England Journal of Medicine. doi:10.1056/nejm198904273201702
Needleman and colleagues found children with high lead levels in their teeth (dentine) scored lower on IQ, speech-processing and attention tests than children with low levels, and teacher-rated classroom problems rose with dentine lead.
As reported in: Needleman, Gunnoe, Leviton et al. (1979). Deficits in Psychologic and Classroom Performance of Children with Elevated Dentine Lead Levels. New England Journal of Medicine. doi:10.1056/nejm197903293001301
