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 Lead and Copper Rule The Lead and Copper Rule (LCR) is a United States federal regulation which limits the concentration of lead and copper allowed in public drinking water at the consumer's tap, as well as limiting the permissible amount of pipe corrosion occurring due to the water itself. The U.S. Environmental Protection Agency (EPA) first issued the rule in 1991 pursuant to the Safe Drinking Water Act. EPA promulgated the regulations following studies that concluded that copper and lead have an adverse effect on individuals. The LCR sought to therefore limit the levels of these metals in water through
