Fig. 2: The association between upwind O&G production activities and downwind level of PR.
From: Unconventional oil and gas development and ambient particle radioactivity

The increase in PR associated with an additional 100 UOGD wells (blue bars) and COGD wells (red bars) at multiple buffer distance. Effect estimations are visualized as the points and the 95% Cis are visualized as the bars. The source data of this figure is provided in Supplementary Table 2.
