Abstract:
Possibility of separation of no-carrier-added (NCA) astatine radionuclides from the bulk lead-bismuth-eutectic (LBE) target was explored in a simple way in the laboratory scale. A LBE target was irradiated by 40MeV α-particles delivered from a cyclotron facility, India. Quantitative analysis of the irradiated target indicated the production of 210,209At, 207Po radionuclides in the target matrix. The 210,209At radionuclides were separated by precipitation of bulk Pb, Bi and NCA radiotoxic Po radionuclides.
