The radium

There is almost no piece of land where there would not be any trace of the radium. In any breed it is about 0,000000001 percent, that is ten thousand times less than gold or silver. But no matter how insignificant this content is, in a land up to ten kilometers deep there are about a million tons of radium. The power of this amount of radium is incomparable neither with gold nor with silver. A pinch of radium constantly emits miraculous rays-particles, some of which are imperceptibly transformed into a wonderful gas the Sun - the helium. From this small pinch of heat constantly stands out, and only after two thousand years it will be half weakened. In addition, radium shines with its rays, rushing with speed of light in some cases and at a speed of 20000 kilometers per second - in others. It heats for thousands of years, and so that one gram of radium can heat up to boiling twenty-five cubic centimeters of water per hour. Sometimes radium burns a person to wounds, and sometimes saves from death, for example, heals a serious disease - cancer.

The radium was discovered by French scientists Pierre and Maria Curie, who discovered that the waste that remains after uranium is separated from uranium ore is more radioactive than pure uranium. From these wastes of the Curie couple, after several years of intensive work, two highly radioactive elements were singled out: polonium and radium. Radium is formed through many intermediate stages in the radioactive decay of the uranium-238 isotope.

More than a hundredths of a milligram per hundred grams of radium is never found, and science says that more content is impossible. But in reality the ore is much poorer. Over the past since its opening time - more than a century - the world has managed to extract only 1.5 kg of pure radium. Radium is mined in Central Africa, Polar Canada, the Czech Republic and in the Alai and Colorado Mountains.

Hard work extracts crystalline ore, the so-called "ore marble" - a red or green dark calcareous rock, in which only visible patches of yellow crystals of radium mineral. After that, the ore passes a long and complicated path to the radium plant. There begins a new and complex path of its transformations, the allocation of valuable radium from it. Many hundreds of tons of ore must be raised from the mine, dissolved and processed at the plant, so that at least one gram of radiant radium salt is released...

The beginning of the Tertiary era has come - that momentous moment in the history of Earth, when again along the old lines, a new, young Alpine mountain system began to uplift its folds, move and tilt layers, pushing powerful old massifs onto young sediments, breaking and splitting the earth's crust before them. Here still powerful chemical processes are going on in the inaccessible depths of the Earth. Here, solutions of radium salts also rose...

And at the same time, in a moderately humid but uneven climate, that kind of surface change that we call karst. Waters of rain over the cracks began to penetrate into the limestones, began to dissolve their walls, washing their way and crashing into long and complex passages into the limestone.

And now, in these karstic cavities and penetrated hot waters of depths with their enigmatic accumulations of uranium, vanadium, copper and barium. With them from the unknown depths came and radium...
