text: Despite having a similar half-life to the previous isotope (8.1 hours for astatine-210 and 7.2 hours for astatine-211), the alpha decay probability is much higher for the latter: 41.81% against only 0.18%.[j]

text: The longest-lived isotope of francium has a half-life of just 22 minutes (some isotopes actually decay into astatine), while that of the most stable isotope of astatine (210At, which does not occur naturally) is 8.1 hours.
