What is the Linear-No-Threshold hypothesis?
The Linear-No-Threshold hypothesis states that any exposure to radiation, no matter how low, could result in an increased projected cancer risk and that there is a dose response relationship to elevated cancer risk with higher exposures. Considerable controversy exists surrounding the extrapolation of projected cancer risk to low-level exposure in medical testing, and no reported evidence links low-level exposure to observed cancer risk. Even when the Linear-No-Threshold hypothesis is used, the projected incident cancer is estimated to be very low for nuclear MPI and CCTA.
