Radium is a naturally occurring silvery-white radioactive metal that can exist in several forms called isotopes. Radium is formed when uranium and thorium break down in the environment. Uranium and thorium are found in small amounts in most rocks and soil. Two of the main radium isotopes found in the environment are radium-226 and radium-228. Radium undergoes …

This is a nice, very active uranium sample that's useful for testing geiger counters. It came in a metal container with a certification document from "Images SI Inc." stating that they tested the sample and measured 1,682 CPM using their GCA-07W geiger counter.

Radium and uranium concentrations in water from 37 wells tapping the aquifer system of the Dakota Sandstone and Purgatoire Formation in southwestern Pueblo County, Colorado, have a wide range of values and define several aro^s of high radioactivity in …

The uranium series, known also as radium series, is one of three classical radioactive series beginning with naturally occurring uranium-238.This radioactive decay chain consists of unstable heavy atomic nuclei that decay through a sequence of alpha and beta decays until a stable nucleus is achieved. In case of uranium series, the stable nucleus is lead-206.

The Radium were factory workers who contracted radiation poisoning from painting watch dials with self-luminous paint. The painting was done by women at three different factories, and the term now applies to the women working at the facilities: one in Orange, New Jersey, beginning around 1917; one in Ottawa, Illinois, beginning in the early 1920s; and a third facility …

Uranium is an element that has been in rocks since the earth was formed. Not all rocks contain uranium, but there are many places where uranium is in the bedrock. Other elements that may be found in association with uranium include radium and radon. Natural uranium is not radioactive enough to be useful in nuclear power plants or weapons.

RADIUM-226 AND 228 What is RADIUM-226 and 228? Radium is a silvery-white metal that is radioactive. It sends out energy in the form of rays, waves or particles. It is found in nature and can exist in several forms. Radium forms when two other chemicals (uranium and thorium) break down in most rocks and soil. Radium will undergo radioactive decay.
