This application relates to a polymer scintillation fiber drawing furnace, a drawing method, and a polymer scintillation fiber, belonging to the field of fiber optic fabrication technology. The polymer scintillation fiber drawing furnace of this application includes a furnace body and an infrared heating unit. The furnace body has a heating cavity inside, with an inlet and an outlet at each end communicating with the heating cavity. This allows a polymer scintillation fiber preform to be inserted through the inlet and the polymer scintillation fiber to be drawn out through the outlet. The infrared heating unit is located around the periphery of the heating cavity, enabling heating of a predetermined range of the polymer scintillation fiber preform from different peripheral positions. This reduces the decomposition of fluorescent dyes in the scintillation fiber, ensuring the sensitivity of the scintillation fiber in detecting high-energy radiation. This application also discloses a polymer scintillation fiber drawing method and a polymer scintillation fiber.
