摘要
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. The detection data set is limited to a period between the triggering action and a particular measurement interval.
