Abstract: A method of detecting radon may include starting a first timer at a radon detection device in response to a first triggering action. A seal of the radon detection device may transition to a seal position from an open position in response to the first timer being equal to a measurement interval. The open position may facilitate the introduction of ambient air to a vent of the radon detection device. The seal position may discourage introduction of the ambient air to the vent. The vent may be in fluid communication with a test material. The test material may collect radon from the ambient air introduced to the radon detection device. A second timer may be started in response to the seal transitioning from the open position to the seal position. The seal remains in the sealed position following the transition from the open position to the sealed position.

Abstract: A radon measurement device includes a housing, a diffusion chamber, a diffusion chamber sensor, a diffusion pathway, a clock circuit, measurement circuitry, and a triggering mechanism. The diffusion chamber is disposed in an internal cavity of the housing. The housing includes a vent. The diffusion chamber sensor detects radioactive decay of radon and generates an electrical signal. The diffusion pathway enables introduction of ambient air into the diffusion chamber. The clock circuit outputs time data. The measurement circuitry receives the electrical signal and associates therewith a particular time datum. The triggering mechanism selectively isolates the vent from an environment and selectively triggers the measurement circuitry. Responsive to a triggering action on the triggering mechanism, the diffusion pathway is fluidly connected with the environment and functionality of the measurement circuitry is initiated.
