Radon half-life measured to be 90.71 +- 11.25 hrs from the data, using the actual radon half-life of 91.3 hours it would take about 22 days for the radon levels to reach 0.1 mBq/kg. The half-life equation is y = 0.000 + 34.66*exp(-x/90.71 hrs) mBq/kg. The U238 limit is based on the uncertainty of the y-intercept term (0.000 ± 1.099). |

Radon half-life measured to be 88.88 +- 13.54 hrs from the data, using the actual radon half-life of 91.3 hours it would take about 22 days for the radon levels to reach 0.1 mBq/kg. The half-life equation is y = 0.00 + 28.04 * exp(-x/ 91.3 hrs) mBq/kg. The U238 limit is based on the uncertainty of the y-intercept term (0.000 ± 0.954). |
