While investigating facts about Caesium 137, I found out little known, but curios details like:

In 1987 two Brazilian men looking for scrap, unknowinlgy stole a teletherapy unit, along with the highly radioactive Caesium 137 in it, took it home and tried to dismantle it, directly killing 4 and contaminating 250 people in their wake.
