One study that investigated brain samples from 29 deceased patients, 11 with Alzheimer disease, six with Parkinson disease, and eight controls with no evidence of neurological disorders, found a tenfold increase in radioactivity of long-lived radon progeny polonium-210 and lead-210 in the brains of those with neurological dysfunction in comparison with the controls.

Ter Haar GL, Holtzman RB, Lucas HF Jr. PMID: 5302720 [Indexed for MEDLINE] MeSH terms Lead-210 occurs in the environment and its natural variability, as well as the importance of establishing background levels on a media specific basis, before drawing conclusions about the presence of contamina-tion. Several research papers note a natural abundance of Lead-210 in sediments that are generally consistent with these levels: lead. (Pb) ( led) A metallic element, atomic no. 82, atomic wt.

Americium-241 (half-life: 432 yr): Used in backscatter gauges, smoke detectors, fill height detectors, and in measuring ash content of coal. Caesium-137 (30 After it is extracted from the ground, however, lead-210 decays into more stable isotopes, with the concentration of the radioactive isotope halving every 22 years. The mass of an atom relative to that of carbon-12. This is approximately the sum of the number of protons and neutrons in the nucleus. Where more than one isotope exists, the value given is the abundance weighted average. Isotopes Atoms of the same element with different numbers of neutrons.
