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
Lead and Copper Rule home, the water supplier may leave the sample bottles and sampling instructions with the consumer. EPA was investigated by the Government Accountability Office (GAO) in 2003 following the discovery of higher-than-acceptable copper and lead levels in tap water in the District of Columbia. The GAO reported that EPA had not been collecting copper and lead levels from the states, despite claims that the levels of copper and lead have decreased; data for 72 percent of water systems were missing. EPA may have been lacking data because more resources were being dedicated to lead regulation than lead reporting. Lead and Copper
