Radioactive decay is nondeterministic.

1 m^3 of air at stp is 1.19kg.

Air contains 1.29% argon by mass. 1 m^3 of air contains 15.3 grams of Ar.

Natural argon is ~8*10^−16 m/m 39Ar. 1 m^3 of air contains 12.2fg of 39Ar.

One atom of 39Ar is 6.47^-23 grams. 1 m^3 of air contains 189 billion atoms of 39Ar.

Halflife of 39Ar is 269 years. 1 m^3 of air will have one beta-decay of 39Ar every 90ms on average.
