Copper-64 specific activity (the number of decays per second per amount of substance) and low yield through the Cu(n,γ)Cu reaction. At the University of Missouri Research Reactor Center (MURR) Cu was produced using high-energy neutrons via the Zn(n,p)Cu reaction in high specific activity but low yield. Using a biomedical cyclotron the Ni(p,n)Cu nuclear reaction can produce large quantities of the nuclide with high specific activity. Wilson’s disease is a rare condition in which copper is retained excessively in the body. Toxic levels of copper can lead to organ failure and premature death. Cu is used to study whole body retention of
Brain Damage (song) Brain Damage (song) "Brain Damage" is the ninth track from English rock band Pink Floyd's 1973 album "The Dark Side of the Moon". It was sung on record by Roger Waters (with harmonies by David Gilmour), who would continue to sing it on his solo tours. Gilmour sang the lead vocal when Pink Floyd performed it live on their 1994 tour (as can be heard on "Pulse"). The band originally called this track "Lunatic" during live performances and recording sessions. When the band reconvened after the American leg of the "Meddle" tour, Roger Waters brought with him a prototype version
