Alpha emitter
The only
isotope
found on
Earth
because it occurs
as
part of the
uranium 238 decay chain
,
i
.e., it is not
a
primordial nuclide
.
Interestingly it is
a
bit
less stable than other
isotopes
L
such
as
Polonium-208
(
3
y
) and
Polonium-209
(124
y)
, but those aren'
t
in any Earthly radioactive chain so they don'
t
show up on
Earth
.
