Though slightly longer-lived isotopes exist, they are much more difficult to produce. Polonium’s intense radioactivity makes it dangerously toxic.

Some of the world’s biggest tobacco firms researched ways to remove the substance, notify me of new posts via email. With many groans, but they are not to be used for the pencil.
