2026-06-23 Raw dataset for the study on the method of simultaneous regulation of ²²²Rn/²²⁰Rn progeny activity concentration in ²²⁰Rn chamber doi:10.57760/sciencedb.j00186.01127 en This dataset originates from sampling and measurement experiments of ²²²Rn and ²²⁰Rn progeny inside a ²²⁰Rn chamber. A dedicated sampler was used to collect the decay progeny of ²²²Rn and ²²⁰Rn in indoor air onto filter membranes, followed by α-spectrometry measurement of the progeny deposited on the filters using an α spectrometer. By analyzing the measured spectral data via α-spectrometry, the activity concentrations of ²²²Rn and ²²⁰Rn progeny inside the chamber can be derived. The dataset primarily records the α-spectrometry multi-channel counts (N1–N5, corresponding to different energy windows) under various experimental conditions, including radon/thoron concentrations, temperature, humidity, and sampling type (filter membrane/wire mesh). ²²²Rn/²²⁰Rn progeny; simultaneous regulation; ²²⁰Rn chamber 敖韬 RESTRICTED dataset Science Data Bank
