Also referred to as pleural effusion or ' fluid on lungs ', the condition is commonly diagnosed among TB patients. Normally, there is a small amount of fluid surrounding the lungs but in TB there is bacterial growth in the fluid filled space between the chest wall and the lungs.
Following are the equations of several nuclear reactions that have important roles in the history of nuclear chemistry: 1  The first naturally occurring unstable element that was isolated, polonium, was discovered by the Polish scientist Marie Curie and her husband Pierre in 1898. It decays, emitting Î± particles:
This discovery of spontaneous âradioactivityâ (a term coined by Becquerelâs doctoral student, Marie Curie) eventually earned Becquerel a Nobel Prize for Physics in 1903, which he shared with Marie Curie and her husband Pierre Curie.enchmarks: Henri Becquerel discovers radioactivity on February 26, 1896. Credit: A photographic plate made by Henri Becquerel shows the effects of exposure to radioactivity. A metal Maltese cross, placed between the plate and radioactive uranium salt, left a clearly visible shadow on the plate.
