No-carrier-added (nca) 208,209,210At was produced for the first time from 9Be induced reaction on thallium carbonate target at BARC-TIFR pelletron, Mumbai, India. The target of 4 mg/cm2 thickness was prepared by centrifugation technique. Nca At was separated from the thallium target by liquid–liquid extraction using liquid cation exchanger HDEHP dissolved in cyclohexane and liquor ammonia. 
Separation of no-carrier-added astatine radionuclides from α-particle irradiated lead bismuth eutectic target: A classical method.
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 wasExpand
