DEVICE AND METHOD FOR MEASURING RADON RELEASE AMOUNT DURING ROCK SHEARING DAMAGE PROCESS

摘要

The disclosure provides a device and method for measuring radon release amount during rock shearing damage process. The method includes: the sealed chamber where the rock sample placed is vacuumed in the first place, and then the radon released during rock sample shearing damage process is all collected into the radon collection box, and then the concentration of the radon collected in the radon collection box is measured with a radon concentration measure instrument, so that the purity of the radon collected in the radon collection box can be ensured, and thus the accuracy of the concentration of radon measured by the radon concentration measure instrument can be ensured, and the device and method have good practicability.
