1. Also provided are methods for increasing the radiochemical yield of an actinium-225-chelant-biomolecule complex and for producing a high specific activity actinium-225 complex.

2. Sucrose metabolism by resting-cell suspensions of pure cultures of representative members of the predominant cultivable flora isolated from Cariogenic and non-Cariogenic dental plaque was investigated by means of radiochemical techniques

3. Many subsequent radiochemical and water Cherenkov detectors confirmed the deficit, but neutrino oscillation was not conclusively identified as the source of the deficit until the Sudbury Neutrino Observatory provided clear evidence of neutrino flavor change in 2001.
