用中子束照射铀箔测量２３８Ｕ裂变率时，由于铀箔含有少量的２３５Ｕ原子，所以测量结果必须去掉２３８Ｕ的裂变率而加以修正。本文介绍一种箔活化法测量２３８Ｕ裂变率的修正方法，它用于修正用铀箔测量２３８Ｕ裂变率分布，修正后的２３８Ｕ裂变率和用包镉裂变室测量数据进行了比较，其结果是令人满意的。
Measurement of 238U fission rate with neutron beam irradiation with uranium foil Since the uranium foil contains a small amount of 235U atoms, the measurement result must be corrected by removing the fission rate of 238U. This paper presents a modified method of foil activation to measure the fission rate of 238U, which is used to correct the 238U fission rate distribution measured with uranium foil, the corrected 238U fission rate and the comparison with the fission chamber data. The result is that Satisfied.
