Radon Decay Products
A term used to refer collectively to the immediate products of the radon decay chain. These include Po-218, Pb-214, Bi-214, and Po-214, which have an average combined half-life of about 30 minutes.
Decay Products
Degraded radioactive materials, often referred to, as "daughters or progeny"; radon decay products of most concern from a public health standpoint are polonium-214 and polonium-218.
De-chlorination ...
The decay products may be derived from their immediate predecessor, of through several other decays in a decay chain series.
Short-lived radioactive decay products of radon that decay into longer-lived lead isotopes. The daughter isotopes can attach themselves to airborne dust and other particles and, if inhaled, damage the lining of the lung.
Working Level (WL)- A unit of measure for documenting exposure to radon decay products, the so-called "daughters." One working level is equal to approximately 200 picocuries per liter.
