Method for long-term measurement of exhalation rate of radon from e.g. ground surface, involves conveying air into collection container during rinsing phase, and sealing container against environment after rinsing phase

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a method and device for long-term measurement of the rate at which gaseous substances such as radon are released, for example from the ground surface. The system uses a collection container, which is periodically rinsed with air to reset gas concentration before sealing it again to measure the accumulation of the gas, allowing accurate determination of exhalation rates over time.

Patent Abstract

The method involves collecting a gaseous substance in a collection container (1) that is sealed against surrounding air, and determining a measuring variable in a measuring phase, where the variable represents concentration of the substance in the container. The surrounding air is actively conveyed into the container during a rinsing phase such that the concentration of the substance in the container is lowered. The container is again sealed against environment after the rinsing phase. Exhalation rate of the substance is evaluated based on the concentration of the substance in the container. An independent claim is also included for a device for long-term measurement of an exhalation rate of a gaseous substance.
