Radiation is a phenomenon characterized more by its ability to canse biological effects than where it originates. Radiation was hrst discovered by German scientist Antoine Henri Becquerel, who received the Nobel Prize of Physics in 1903 for his work. Many of the terms associated with radioactivity come from those early pioneers in radiation physics Wilhelm Conrad Roentgen (1845-1923) and Pierre (1859-1906) and Marie Curie (1867-1934), who also received the Nobel Prize in Physics in 1903 for their work on radiation. Ernest Rutherford (1871-1937) is considered the father of nuclear physics. He developed the language that describes the theoretical concepts of the atom and the phenomenon of radioactivity. Particles named and characterized by him include the alpha particle, beta particle, and proton. Rutherford won the Nobel Prize for Chemistry in 1909 for his work. 

In mid-2003, the joint working party assigned credit for discovery of element 111 to the GSI group and asked them to propose a name (Karol et al., 2003), but the evidence for discovery of element 112 was still deemed insufficient. The name roentgenium, symbol Rg, in honor of Wilhelm Conrad Roentgen, who discovered X-rays in 1895, was proposed for element 111 by the discovery group. In May 2004 a provisional recommendation for approval of the proposal (Corish and Rosenblatt, 2004) was sent to the IUPAC Bureau and Council, and it was approved in November 2004. 

On November 1,2004, the lUPAC officially approved the name roentgenium, symbol Rg, for the element of atomic number 111. Roentgenium was named for Wilhelm Conrad Roentgen, who discovered X-rays in 1895. The nuclear equation for its formation is...
