A Fast Inexpensive Way to Analyze for Uranium and Radium ...
So Radium and Uranium concentrations in soils are normally determined by putting a small quantity of the soil into solution by a pyrosulfate or NaOH fusion, and then separating the uranium and thorium by extraction chromatography and counting. This is time consuming and expensive.

Rapid Analysis of Radium-226 in Water Samples by ICP
2017-8-9 Radium-226 is a radionuclide that occurs naturally as part of the uranium-238 decay series. 226Ra decays with a half-life of 1,600 years to radon-222 with the emission of alpha and gamma radiation. The element is known for its historical use in the luminescent paint used in clocks, watches, and other instruments. These uses led to severe health problems for the so-called Radium Girls who

It has been employed over the last seven decades as a source of energy and weapon. Enrichment processes were widely practiced to produce the necessary fuel. On the other hand, depleted uranium (DU) was also produced as a by-product of this
