• The correction factor P(<I>t</I>) used in determining the fast fission effect of <SUP>238</SUP>U was measured in the range of cooling time <I>t</I>= 30200 min for irradiations of 30 min, 2 and 5 hr, respectively. This factor depends quite sensitively on the bias level in γ-ray counting as well as on the irradiation time and cooling time after irradiation. It is emphasized that neglect of the depend-ence of <I>P</I>(<I>t</I>) on irradiation time and bias level results in a large error in measurements of fast fission effect of <SUP>238</SUP>U.
