Read an invented growth curve
Toy relationship: R=1−exp(−D/50). Dose units and response are invented, with no mineral calibration.
No actual equivalent dose or age is estimated. The comparison uses R ± 0.02, limited here to 0.001–0.999. At R=1, the inferred dose has no finite value. This is an illustration, not a measured confidence interval. Real analysis includes sensitivity correction and protocol checks.
