People of the press and of the left:
If an isotope has a long half-life it is NOT highly radioactive.
Exposure to an element with a long half-life does NOT mean instant death by radiation poisoning.
Give me a pocket full of Radium-226 (half-life 1621 years) any time over Radium-228 (half life 5.8 years).
Edited to add: .. and human flesh doesn't "glow in the dark" after heavy exposure to ionising radition - it dies.
