The radiations of Ptlg7 have been examined with coincident spectrometers of NaI-TI and anthracene. Gamma rays have been detected at 77, 191, and 279 Kev, the unconverted quantum radiations having relative intensities of 30, 3.9, and 1.0. Coincidence measurements revealed the presence of three beta

The characteristic radiations of the 36-hr. rhodium (105) have been investigated with the use of conventional absorption and coincidence methods. The beta rays were found to have a maximum energy of 0.55 Mev., and the gamma rays a quantum energy of ~-~0.3 Mev. The beta-gamma coincidence rate of Rh 1

Zr9602 (isotopic concentration 90 per cent) was irradiated by slow neutrons in the Oak Ridge pile. The half-period of the niobium daughter element, chemically separated from zirconium, was found to be 72.1 ~ 0.7 rain. and that of Zr 97 to be 17.0 + 0.2 hr. By aluminum absorption and Feather analysis
