Half life (intermediate)

The $106$106th element, seaborgium, was created artificially in $1974$1974 by bombarding heavy nuclei with lighter ones at the HILAC collider (shown below).

Say, an unknown amount of seaborgium nuclides is produced at time, $t=0.0\ \text s$t, equals, 0, point, 0, space, start text, s, end text.

The instruments detect $32\ \text{moles}$32, space, start text, m, o, l, e, s, end text at $t=2.0\ \text s$t, equals, 2, point, 0, space, start text, s, end text, which reduces to only $2.0\ \text{moles}$2, point, 0, space, start text, m, o, l, e, s, end text at $t=6.0\ \text s$t, equals, 6, point, 0, space, start text, s, end text.
