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:
Polonium was the first element discovered by Marie Sklodowska Curie in 1898, while seeking the cause of radioactivity of pitchblende from Joachimsthal, Bohemia.It required several tonnes of pitchblende to produce very small amounts of polonium.olonium was the first element discovered by Marie Sklodowska Curie in 1898, while seeking the cause of radioactivity of pitchblende from Joachimsthal, Bohemia.
