Name the four stages of ARS. 

For each of the radiation dose-response curves, describe whether each is linear, linear-quadratic, or sigmoid; whether it possesses a threshold or nonthreshold; and give an example of what the curve could represent (hint: type of radiation or type of radiation-induced effect). 1. linear, linear-quadratic, or sigmoid 2. threshold or nonthreshold 3. give an example

If we increase the kVp, the probability of photoelectric absorption  the dose to the patient, the probability of Compton scattering, therefore the amount of scatter and the dose to the radiographer.  This will also the contrast on the image.
