text: Significantly radioactive elements: the most stable isotope has half-life between 800 and 34,000 years.
text: Isotopes of elements beyond californium have half-lives much shorter than one year, meaning that it is the last element in the periodic table that macroscopic chemistry can be reasonably conducted on.
text: Radioactive elements: the most stable isotope has half-life between one day and 130 years.
text: Highly radioactive elements: the most stable isotope has half-life between several minutes and one day.
