The K-conversion coefficient of 58.6 keV (2<sup>+</sup> to 5<sup>+</sup>) M3 gamma transition in <sup>60m</sup>Co and the total conversion coefficient of 479.53 keV (7<sup>+</sup> to 3<sup>-</sup>) M4 gamma transition in <sup>90m</sup>Y were measured by X-ray, gamma -ray and intensity balance methods, respectively, using high-resolution solid-state detectors. The values obtained were alpha <sub>K</sub>=39.04+or-1.90 in <sup>60m</sup>Co and alpha <sub>T</sub>=0.0990+or-0.0013 in <sup>90m</sup>Y. These results are seen to be consistent with the theoretical values due to Rosel and co-workers (1978).
