Given the information about your home, here's a plot of the estimated probability distribution for the radon concentration in your home. The area shaded in red (if any) shows the probability that your home's annual-average, living-area concentration exceeds the level 4.0 at which you said you would remediate. [This distribution has a median of 1.4 and a geometric standard deviation of 1.6 ]

We evaluated four possible actions that you could take. These are summarized in the table below. Given your stated risk tolerance, we recommend the highlighted action.

  Immediate cost ($) Probability that you will remediate if you follow this strategy Expected total cost ($) Expected lives saved compared to no action
Remediate Immediately 2000 1.00 2000 0.000
Make a year-long measurement and fix your house if the result exceeds 4.60 pCi/L. 50 0.01 64 0.000
Make a short-term measurement and fix your house if the measurement is over 28.20 pCi/L 15 0.00 15 0.000
Do nothing 0 0.00 0 0.000
