Heldigvis er det kun den syntetiske #strontium-90 der er radioaktiv:

While natural strontium (which is mostly the isotope strontium-88) is stable, the synthetic strontium-90 is radioactive and is one of the most dangerous components of nuclear fallout, as strontium is absorbed by the body in a similar manner to calcium. Natural stable strontium is not hazardous to health at low levels. H2G2

Se evt. osse doi:10.3390/jfb15080216 om anvendelse af bioaktive strontium­forbindelser indenfor tandlæge­videnskaben.

Det er lidt af et kaninhul at ryge ned i. 😁
