Name 3 major types of late somatic effects.

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.
