This rarely seen metal is most typically associated with nuclear pollution. Finding the strontium-90 isotope in the atmosphere around your neighborhood is bad news indeed and should be cause for immediate plans to relocate to your mother-in-law's for a while. But don't worry, that should only happen if you live near a malfunctioning nuclear power plant.

Strontium's other isotopes are considerably less harmful. In fact, one big use of it goes into toothpaste because it coats teeth in a microscopic film that protects against cavities. The piece here would be enough to seal a city's worth of its denizen's teeth. We really don't recommend chewing on it though.

The root-like samples of strontium we carry are formed as the metal cools from a molten state growing out in branches according to its preferred atomic planes. Since the metal is very reactive in air we prevent it from rusting completely by keeping it in mineral oil.
