摘要：The dose values of β, γ and х rays are important factors for evaluating the radioactivity in the environment, and monitoring the dose values of these rays in the environment is the primary measure to achieve radiation protection. Therefore, in view of the shortcomings of high power consumption and inconvenient carrying of some dosimeters at home and abroad, a new type of nuclear radiation dosimeter adapted to the new model was made, and the main parameters were measured. The dosimeter designed in this paper is a new type of nuclear radiation dosimeter mainly based on G-M counter tube and Atmega 8 main controller. This paper designs the circuit of the instrument and adjusts the parameters of the circuit to ensure the stability of the instrument and make the instrument work for a long time.
