The invention provides a PING monitor prototype radon chamber test method, device and equipment and a storage medium, and aims to solve the technical problem of poor performance evaluation accuracy of a PING monitor prototype. The test method comprises the following steps: extracting gas to be tested; S10, acquiring the activity concentration of radon gas and the equilibrium equivalent concentration of radon daughters in the gas to be tested; a gas detection step S20, detecting to obtain an alpha particle net counting rate and a first beta particle net counting rate; s30, determining a radon daughter response coefficient, and determining a radon daughter response coefficient and compensation coefficient curve; s40, the response coefficient of the radon daughters is compensated, and the response coefficient of the radon daughters after compensation is obtained; a second beta particle net counting rate detection step S50, obtaining a second beta particle net counting rate; a radon gas response coefficient detection step S60, determining a radon gas response coefficient; and a monitor prototype evaluation step S70, evaluating the performance of the monitor prototype according to the compensated radon daughter response coefficient and the radon gas response coefficient.

The application discloses an environment-friendly and saving radon chamber, a radon concentration control method thereof and electronic equipment. The environment-friendly and saving radon chamber is provided with a separate radon buffer storage chamber. When the radon chamber does not need radon supplement, the three-way valve and the air pump are both closed, and the radon gas is self-circulated in the radon storage tank to realize radioactive balance. When the radon chamber needs radon supplement, the three-way valve and the air pump are both opened, the radon storage tank is connected with the radon chamber, and the radon gas in the radon storage tank is pumped to the radon chamber by the air pump to realize the radon supplement function. Therefore, the closed loop circulation and accurate scheduling of the radon gas in the system are realized, and the radon concentration of the radon chamber is dynamically controlled. The technical scheme provided in the embodiment of the application completely encloses the radon gas generated by the radon source in the system for recycling, which not only eliminates the environmental pollution and health risks of radioactive waste gas emission, but also maximizes the utilization rate of the radon source.
