Abstract: Along with β radiation of ²³⁸U and ²³⁵U dacay in uranium fuel. Existing, weakly penetrating radiation risk ofto operator of uranium fuel element exists. TIn this article,measuring the β spectrum was measured with β spectrometer and measuring the β dose rate was measured with directional dose equivalent meter,T, while the maximum energy of beta ray emitted from uranium fuel element is 2.3 MeV. The measurement results show that the $\dot{H}$'(0.07) is 1.38 mSv/h, and the $\dot{H}$'(0.07)/$\dot{H}$^*(10) is 36. The experimental results show that the protective clothing worn by the uranium fuel element operators has almost no protective effect on high-energy β rays, and the H_p(0.07)/H_p(10) is 130. AccordingBased on the measurement results of uranium fuel element and operator, it is suggested monitoring H_p(0.07) and H_p(3) for the operator of uranium fuel element. At the same time,, the weakly penetrating radiation protectiveon methods were provided.

Key words: uranium fuel element, $\dot{H}$'(0.07), ($\dot{H}$)^*(10), H_p(0.07), H_p(10)
