Thus, the short-lived typo can have an activity equal to the 222Rn because a large decay constant times a small number of atoms becomes equal to a small decay constant times a large number of atoms.
(the short-lived typo; can have; an activity equal to the 222Rn; because a large decay constant times a small number of atoms becomes equal to a small decay constant times) (a small number of atoms; becomes; equal to a small decay constant times)
the short-lived typo a small number of atoms
can have becomes
an activity equal to the 222Rn because a large decay constant times a small number of atoms becomes equal to a small decay constant times
equal to a small decay constant times
