The PB-203 radioisotope, manufactured by PATOLA, is a key component in advanced radiopharmaceutical research. It possesses a physical half-life of 52.1 hours and decays via electron capture to stable Tl-203. This radionuclide emits gamma rays suitable for imaging with standard gamma cameras, enabling precise diagnostic capabilities.
PB-203 is particularly noted for its role as a SPECT imaging source, forming a theranostic pair with Pb-212 for image-guided cancer treatment. Its properties allow for targeted damage to cancer cells while sparing healthy tissue, addressing critical challenges in oncology research. Handling precautions include appropriate shielding and radiation detection instruments due to its unshielded exposure rate.
Available in volumes from 0.02 to 5 ml with activities ranging from 3 to 200 mCi, PB-203 is supplied as Lead Chloride (PbCl2) in 0.5 M HCl. Occupational exposure limits are defined by USNRC 10 CFR 20 for Class D compounds.
