Individual radiation dosimeter for deepwater operation and early warning method

The invention belongs to the technical field of radiation dose detection, and solves the problems that a personal radiation dosimeter is not suitable for an underwater radiation place, and a user is flurried in a complex deepwater environment due to emergency early warning. According to the deepwater operation personal radiation dosimeter and the early warning method, a microcontroller module converts the counting rate collected by a detector into the current radiation dose rate and the current radiation accumulated dose and calculates the remaining working duration in the current environment, and the microcontroller module controls the broadcasting frequency of a voice broadcasting module according to the remaining working duration; the broadcast voice is transmitted to the bone conduction earphone; and the data communication module can be connected with an upper computer through a data reader and performs data exchange with the upper computer. According to the invention, voice broadcast content is transmitt
