Conversion coefficient of 800 keV γ-rays from the decay of Polonium-210 has been measured using scintillation method to be 0.039 ± 0.01. The value of conversion coefficient has also been obtained by the measurement of conversion electrons with an end window type G.M. counter. The absorption curve for electrons is given and its shape has been interpreted in the light of the results ofAlphonse Lagasse andJacqueline Doyeb (Compt. Rend.,239, (11), 670 (1954)). The value of conversion coefficient obtained in this way is 0.014 ± 0.005. The discrepancy between the two values has been explained as due toK andL shell ionization by α-particles. No coincidences were found between the different parts of γ-ray spectrum.
