Cyclotron production of a 204Bi/204mPb generator by 24 MeV proton irradiation of natural Pb foil targets

Journal Article · · Applied Radiation and Isotopes
This work focuses on the formation of a generator of 204Bi/204mPb for future applications in perturbed angular correlation spectroscopy and biological radiotracing with lead and bismuth isotopes. Generators were formed from the irradiation of natural Pb targets with 24 MeV protons producing 203,204,205,206,207Bi that were rapidly dissolved in 3 M HNO3 and 30 % H2O2 and exchanged into a 0.1 M HCl matrix. Use of 100 mg anion exchange resin (AG 1-x8) allowed 203,204mPb to be eluted in 600 μL of 0.1 M HCl. Furthermore, the longer-lived 205,206Bi were eluted in 5 mL or 3 mL of either 0.25 M sodium acetate buffer pH 4.4 or 1.0 M H2SO4. Initial radiolabeling was conducted with eluted 206Bi using DTPA and DOTA and 203Pb using TCMC-Azide.
