Concentrations of radium, radium, and radium measured separately were greatest in water from the southern part of the aquifer outcrop area. In water from the northern part of the aquifer system outcrop area, radium concentrations were as high as 3. Results of this study confirm these earlier findings.

The most common isotopes isotopes A form of an element that has the same number of protons but a different number of neutrons in the nucleus, giving it a different atomic mass. For example, uranium has thirty-seven different isotopes, including uranium and uranium Radium is part of the uranium decay series decay series The series of decays or transformations that radionuclides go through before reaching a stable form.
For example, the decay chain that begins with Uranium culminates in Lead, after forming intermediates such as Uranium, Thorium, Radium, and Radon Also called the "decay series. Radium and Ra are part of the thorium decay series. All isotopes of radium are radioactive. Radium decays to produce radon gas. Half-life : Radium 5. In the natural environment, radium occurs at trace levels in virtually all rock, soil, water, plants and animals. In areas where radium concentrations in rocks and soils are higher, the groundwater also typically has relatively higher radium content.
Milling of uranium concentrates radium in the tailings. Uranium mining also results in higher levels of radium in nearby water. Radium may concentrate in fish and other aquatic animals. Plants and vegetation may take up radium from the soil. Everyone has some exposure to radium because it is naturally occurring in the environment.
Individuals may be exposed to higher levels of radium if they live in an area where there are higher levels of radium in rock and soil. Radium concentrations in food and air are very low. The concentration of radium in drinking water is generally low, but some regions have higher concentrations due to local geology.
The amount of radium allowed in drinking water from community water systems is regulated. Private wells are not regulated. In some geologic formations, oil and gas production can concentrate radium, often in pipe scale.
Working in a uranium mine or in a plant that processes ore can lead to higher exposures.
