AI Technical Summary
Technical Problem
The high cost of existing radon detectors is mainly due to the use of expensive radium-226 radon sources and expensive HD-6 CNC radon chambers.
Method used
The radium-226 radon source was replaced with a lower-cost granite radon source. By introducing ventilation channels and multiple radon detectors, combined with real-time signal acquisition and fan speed control, the radon concentration was accurately increased and stably maintained, reducing operational complexity.
Benefits of technology
This reduces the detection cost of radon detectors, improves the accuracy and repeatability of the detection process, and enhances the practicality and reliability of the detection system.

Abstract
The application discloses a radon gas detector detection method based on a granite radon source and related devices, and the method is applied to a controller in a radon gas detector detection system, the radon gas detector detection system further comprises a granite radon source, a test space and a ventilation fan between the granite radon source and the test space, and the method comprises the following steps: determining a first target concentration, the first target concentration is not less than an alarm concentration of a measured radon gas detector; controlling the ventilation fan to act on the granite radon source, so that the radon gas concentration in the test space meets the first target concentration; obtaining a first signal obtained by the measured radon gas detector detecting radon gas in the test space; and detecting the detection performance of the measured radon gas detector according to the first signal. By implementing the method in the application, the detection cost of the radon gas detector can be reduced.
