I would hazard a guess that it's simply an extremely rare thing to be poisoned by, and the symptons he presented with were such that thalium was the most likely candidate. Bearing in mind that it was a good many days between his exposure to the poison and when he reported for treatment, the substance itself had probably largely broken down in his body, so it would have been difficult to get hold of a sample. By that time, he was being harmed and ultimately killed by the alpha radiation that had been absorbed into his body, which, from what I gather about radiation poisoning, is pretty much what happens: you can be exposed to the radiation on one day, but it'll take a while before the exposure results in symptons and ultimately death.
