ABSTRACT: In nuclear emergencies, it is necessary to estimate the activity of radioactive rapidly and efficiently. This paper proposes an activity estimation method of linear gamma-ray source based on the single Compton scattering of gamma-ray. The paper establishes a physics model of radiation detection, and deduces the relation of the full-energy peak count and the single Compton scattering count. Based on the physics model and the relation of the full-energy peak and single Compton scattering count, the activity estimation method of linear gamma-ray source is built, which can be applied to different shield and the radioactivity of the linear gamma-ray source can be estimated rapidly and efficiently.
