If we have Radan to 22 that begins with a mass of 150 mg, and after 11.4 days, it's now at 18.7 mg. We need to figure out how Maney half lives past one half life would correspond to the 150 g milligrams. Going to half of that 75 mg to half lifes would be the 75 mg going toe.

The decay of radon- 222  Radon-222 has a half-life of 3.82 days and decays by alpha-particle emission to polonium-218), which by further decay through isotopes of lead, bismuth,  understanding the physical meaning of the decay constant and the half-life theoretical prediction of how the radon 222 daughters increase and then decrease  principles of decay and half-life. of members of the radon-222 decay series (Fig . 1).

It does not decay, and therefore has no half-life. When radon gas is allowed to build up in an enclosed space, such as a mine shaft or basement, the radioactive hazard increases enormously because of the build-up of radon progeny.

Radon 222 half life

Radon is a naturally occurring radioactive gas that is odorless and tasteless.
