skos:definition "The short lived 'radioactive' decay products of radon-222.<br/>
This includes the decay chain up to but not including lead-210, namely <br/>polonium-218 (sometimes called radium <br/>
A), lead-214 (radium <br/>
B), <br/>
bismuth-214 (radium C) and polonium-214 (radium C′), plus traces of <br/>astatine-218, thallium-210 (radium C″) and lead-209. Lead-210 (radium D), <br/>which has a 'half-life' of 22.3 years, and its 'radioactive' progeny — bismuth-210 <br/>(radium E) and polonium-210 (radium F), plus traces of mercury-206 and <br/>thallium-206 — are, strictly, progeny of radon-222, but they are not normally <br/>included in the meaning of the term 'radon progeny', because they will not <br/>normally be present in significant amounts in airborne form. The stable decay <br/>product lead-206 is sometimes known as radium G.<br/>" (en)
