Strontium (version 1)
Strontium (version 1) - Periodic Table of Videos
Introduction
This video discusses the element strontium, particularly focusing on its historical significance and chemical properties. The presenter, Professor Martyn Poliakoff, explains why strontium became well-known in the mid-20th century.
Main Points
- Historical Significance:
- Strontium gained attention in the 1950s and 1960s due to atomic bomb testing.
- The radioactive isotope strontium-90 was produced as a byproduct of these tests.
- Chemical Properties and Health Impact:
- Strontium has chemical properties similar to calcium, leading to its incorporation into human bones.
- Strontium-90 became widely dispersed around the world, causing mild radioactivity in human bones and children's teeth.
- Cultural Impact:
- The presence of strontium-90 in the environment led to its mention in protest songs and pop culture during the atomic age.
- Over time, the focus on strontium-90 has diminished, and it no longer features prominently in public discourse.
Conclusion
Strontium's historical significance stems from its association with atomic bomb testing and the resulting environmental and health concerns. While it once symbolized the dangers of nuclear fallout, its prominence has decreased in recent years.
