Metals, metalloids, and radionuclides all are trace elements that occur naturally in the Earth's crust. In small quantities many trace elements are essential for health in all living organisms, but some trace elements can be toxic or cause cancer, and some can bioaccumulate. The USGS investigates where and how trace elements make their way into our Nation's …

by Chris Clemens Introduction: Uranyl-activated green fluorescence is one of the most common fluorescent responses seen under UV light. It occurs in a wide variety of minerals, generally due to one of two conditions: 1.) The inclusion of trace amounts of the uranyl ion, (U02)2+, as a contaminant not normally present in the mineral. Hyalite opal (opal-AN), …

Autunite is a radioactive orthorhombic mineral which results from the hydrothermal alteration of uranium minerals. Used as a uranium ore, it was first discovered in France in 1852. Autunite is one of the more attractive and popular radioactive minerals. To state the obvious, the uranium in its chemical formula provides this radioactivity.

A 1,400 hectare park with four lakes for swimming, a playground for playing, paths for jogging, pavilions for eating. What I didn't know, until recently, is that a CNN investigation has shown that the park is filled with what many see as an invisible enemy: radioactive rocks. "And yes, that is a danger," Coronado Gutiérrez told CNN in an ...

Lake Chagan is the result of a thermonuclear explosion that happened in 1965 at a nuclear test site in Semey, also known as "The Polygon" in Kazakhstan. It was part of a program to examine the possibility of creating and developing a peaceful purpose of nuclear technology for things like making canals and reservoirs, drilling for oil, or moving large masses of earth.

We found higher concentrations of radioactive cesium ((137)Cs) in brown trout (Salmo trutta) than in rainbow trout (Oncorhynchus nerka), and (137)Cs concentrations in brown trout were higher in a lake than in a stream. Our analyses indicated that these differences were primarily due to differences in diet, but that habitat also had an effect.

There simply is none left to form minerals. There are four main radioactive isotopes that have lasted as long as the Earth: Uranium-239 (over 99% of all uranium) with a half-life of 4.5 billion years. Uranium-235 (less than 1% of all uranium) with a half-life of 700 million years. Thorium-232 (100% of Thorium) with a half-life of 14 billion years.

Definition. Radioactivity in minerals are caused by the inclusion of naturally-occurring radioactive elements in the mineral's composition. The degree of radioactivity is dependent on the concentration and isotope present in the mineral. For the most part, minerals that contain potassium ( K ), uranium ( U ), and thorium ( Th ) are radioactive.

• Radioactive minerals may occur either as residual or secondary deposits in soils. • Residual deposits form because of the heavy weight of minerals bearing U & Th. Like gold, they tend to concentrate with coarse gravel in streams, and in black sands on beaches. Radioactive Elements in Soils. 60FY09 – 07/28/209 – Page 16Page 16Title Page 16

Davidite is the last commonly found radioactive mineral discussed in this article, and is the second primary Uranium ore, next to uranite. It is found in pegmatites, also mostly in Europe, the Middle East, and Russia. You may encounter davidite as granular, dark-colored metallic crystals in rock containing mainly nonmetallic minerals.

A eutrophic lake where dissolved-oxygen concentrations are low. Algal blooms can occur under such conditions. Rapidly moving water, such as in a mountain stream or large river, tends to contain a lot of dissolved oxygen, whereas stagnant water contains less. Bacteria in water can consume oxygen as organic matter decays. Thus, excess organic ...

Uranium is a naturally-occurring radioactive element that has been mined and used for its chemical properties for more than a thousand years. It is now primarily used as fuel for nuclear reactors that make electricity. Uranium can be recovered in two ways: by conventional mining of the rock (ore), or by using strong chemicals to dissolve uranium from the rock that is …
