It was observed that the radionuclides identified and quantified from the gamma ray spectral (Apendix2) are decay daughter products of naturally occurring radioactive element [sup.238]U and [sup.232]Th.
If dry-cleaning fluids are found, then it is necessary to employ a combination of methods, including groundwater transport modeling and analysis for daughter products.

Within five months, degradation daughter products were detected, confirming on-going biodegradation.
We can calculate the rock's age by measuring the relative amounts of remaining radioactive parent and its daughter products. And we can determine the "parent" rocks from which the specimen originally descended (or more accurately in this case, "ascended").
This phenomenon was later utilized by many scientists, including Otto Hahn and Lise Meitner, to separate daughter products in radioactive decay sequences, and hence identify new isotopes.
"But given time and control over the process," he adds, "these daughter products do break down into environmentally benign substances, a process which can be monitored using a gas chromatograph." And, says Blake, "All oxidization processes have the potential to produce partial oxidization products.
From this sample, the calculations predict how the particles and daughter products interact with cancerous matter.
He told a congressional committee: "I could make a case, if I wanted to be facetious, where the miners' health was improved by working underground and being subject to radon daughter products. There are some areas in this chart where it shows that the expected number of cases of lung cancer should be so many and the people working in the mines have zero cases."
