Longtime radon alarmist Bill Field sabotages his own argument.
…Scientifically rigorous epidemiology studies in North America and Europe have clearly established the link between radon exposure in the home and lung cancer. It is the leading environmental cause of cancer mortality in the United States and is expected to be the seventh leading cause of cancer death overall this year…
But if you click on the “establish the link,” you get a study that reports:
…Odds ratios (ORs) for lung cancer increased with residential radon concentration. The estimated OR after exposure to radon at a concentration of 100 Bq/m3 in the exposure time window 5 to 30 years before the index date was 1.11 (95% confidence interval = 1.00-1.28)…
Aside from the folly of the weak statistical association, the 95% confidence interval includes the no-effect level of 1.0 — so this result on its face is not statistically significant.
