Polonium and especially radon contribute to the natural environmental radioactivity.
Polonium is an element and was not invented but discovered.
Polonium was discovered by Marie Curie and Pierre Curie in 1898 at Paris, in France.
Polonium was discovered by Marie Curie and Pierre Curie in 1898 at Paris in France.
Polonium was discovered by Marie and Pierre Curie in 1898, who were studying the residues of uranium pitchblende (after uranium separation) from Jachymow; the residue has a greater radioactivity than uranium.
Polonium was discovered in 1898 by Marie Curie and Pierre Curie studying the radioactivity of uranium ores.
Radon-222 undergoes alpha decay to produce polonium-218as a daughter.
Yes, radium and polonium are radioactive elements.
In 1898 polonium had any use.
Radon is a colorless, odorless radioactive gas that can seep into homes and buildings from the ground, potentially causing lung cancer if inhaled in high concentrations. Polonium is a radioactive element that is toxic and can be harmful if ingested or inhaled. Both substances can pose health risks if proper precautions are not taken to reduce exposure.
