Standardization, decay data measurements and evaluation of 64Cu

Implementation of a new separation method to produce qualitatively improved 64Cu

“…64 Cu was historically produced by a nuclear reactor, both by carrier‐added neutron activation 63 Cu(n,γ) 64 Cu and under no‐carrier‐added conditions with fast neutrons by 64 Zn(n,p) 64 Cu . The radionuclide is presently produced using a cyclotron via the 64 Ni(p,n) 64 Cu nuclear reaction, with an incident energy of approximately 11 to 14 MeV, although another option being investigated is the 64 Ni(d,2n) 64 Cu production method .…”

Determination of photon emission probability for the main gamma ray and half-life measurements of 64Cu

“…Within the past 10 years, several laboratories have reported on the measurement of decay data for 64 Cu (Qaim et al 2007, Wanke et al 2010, Luca et al 2012, Bé et al 2012). Many of these studies were conducted by National Metrology Institutes during the course of the development of primary national standards for this radionuclide.…”

“…The first of these was conducted by Singh (2007) as part of the Evaluated Nuclear Data Structure File (ENSDF), while the most recent was performed by Bé et al (2011) as part of the Decay Data Evaluation Project (DDEP). Because they were published subsequent to the ENSDF evaluation, the recent measurements from Wanke et al (2010), Luca et al (2012), and Bé et al (2012) are only considered in the DDEP evaluation. The evaluated half-life from the DDEP evaluation is (12.7004 ± 0.0020) hours (Bé et al 2011), while the ENSDF evaluation gives a recommended half-life of (12.701 ± 0.002) hours (Singh 2007).…”

Role of the Radionuclide Metrology in Nuclear Medicine

“…The precise value of half life is directly used in nuclear medicine units for the calculation of activity at the moment of administration. (Bé et al 2011). RML standardized absolutely solutions from 64 Cu and 68 Ga by the coincidence method .…”
