1. Introduction to Radioactivity December 15, 2011 Natural Radioactivity:-   Pioneer:- Radioactivity was first discovered by a scientist Henry Becquerel in 1896. Definition:- The natural emission of radiations from unstable nuclei is called radioactivity. Explanation:- Henry Becquerel discovered in 1896 that certain elements whose atomic number is greater than 83 (Z>83) are unstable. They are disintegrating themselves and emitting three types of radiations a, ß, and ? continuously. Such elements are called radioactive elements. the process of emitting radiations is known as radioactivity. These radioactive elements ar... (read more) Author: Naveed Ali

4. Uranium tile - radio controlled digital watch - digital dive watches March 11, 2011 Please help improve this article by adding citations to reliable sources. Unsourced material may be challenged and removed. (February 2008) Uranium tiles have been used in the glazing industry for many centuries, as uranium oxide makes an excellent ceramic glaze, and is reasonably abundant on the earth's crust. Not long after Henri Becquerel discovered radioactivity in uranium salts, Madame Curie discovered both polonium and radium as two new radioactive elements also present with uranium. The relatively high specific activity and moderate half-life of 1,600 years of Ra-226, the main radi... (read more) Author: wgfreg thbtn

5. Women Inventors and their Inventions that Brought Considerable Changes in Lifestyle (2) October 04, 2010 Marie Curie was the first person to have honored with two Nobel Prizes.

7. Radioactive Elements in Cigarettes: Why You Should Stop Smoking! September 19, 2010 Radioactive lead isotopes and polonium isotopes get into tobacco because of the radioactivity of soil-based radium. The regions where tobacco is grown are very rich in radium soils, this can also be contributed to by adding fertiliser to the soil. This elemental particle in soil that surrounds tobacco plants releases gas which enables the tiny polonium and lead particles to float free, consequently attaching to bits of dirt and then are carried to the outer covering of tobacco leaves. Since tobacco leaves are covered with many fine hair-like extensions, lead and polonium particles stick and st... (read more) Author: Tricia Jones
