Embodiment Construction
[0065] The invention relates to a measuring device and calculation method for the radon exhalation rate of emanating rock medium under the action of an adjustable pressure difference. By measuring the exudation rate of radon in the emanating rock medium, it is possible to reasonably formulate the environment of the workplace containing radioactive rock media. Impact assessment and ventilation radon prevention design provide useful reference.
