Radium and Polonium.
Polonium and radium isotopes exist in the decay chains of Th-232, U-233, U-235, U-238.
Polonium was discovered by Marie Curie and Pierre Curie in 1898. Radium was discovered by Marie Curie, Pierre Curie and G. Bemont also in 1898. Studying residues of uranium ores Marie Curie and Pierre Curie found that these residues are more radioactive than uranium; they attributed this radioactivity to unknown elements. They isolated these elements and named these elements polonium and radium.

The name curium is derived from the name of the well known family of scientists - Curie.
Radium is a chemical element Polonium is a chemical element Both were discovered by Marie Curie
Polonium is a rare radioactive element with symbol Po and atomic number 84. It was discovered by Marie Curie and her husband Pierre Curie in 1898. Radium is another radioactive element with symbol Ra and atomic number 88. It is also discovered by Marie Curie, and both polonium and radium are highly toxic and carcinogenic.
84th element is polonium (Po). It is in the same Group as Oxygen.
