Strontium-90 is considered especially dangerous because it is chemically similar to calcium, allowing it to be incorporated into bone and teeth, where it can remain for many years and continually irradiate nearby tissues. This can lead to bone cancer, leukemia, and other health problems. While it does have a relatively short half-life of 28 years, it has a moderate level of radioactivity that can still be harmful in the long term.
