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 Films films: On 14 December 2005, the German government banned Brain Damage Films' website from appearing on major search engines such as Google, stating that the website was "reported as illegal by a German regulatory body". On 22 June 2005, the British Board of Film Classification rejected "Traces of Death", stating that "the work presents no journalistic, educational or other justifying context for the images shown." Films produced and distributed by Brain Damage Films are often criticized for their production value and quality. Below is an incomplete selection of films currently distributed by Brain Damage Films. Brain Damage Films Brain Damage
