    Also with a half life of 138 days it’s hardly “one of the most radioactive substances on Earth”.

    A shorter half life generally means it puts out more radiation per hour.

      Yes, and 138 days is far from the shortest. Take Radon-220 for example. It can be found in nature in trace amounts, while having a half life of only 55.6 seconds, while Radon-222 has the longest half-life of all Radon isotopes at 3.8 days.
