About this Program

This program will review the electromagnetic spectrum, and how x-rays relate to other forms. Direct and indirect damage to human chromosomes will be discussed, along with how free radicals can occur. High and low LET will also be compared and contrasted. The Law of Bergonie and Tribondeau and the effect of radiation on various stages of the cell cycle will be explained.

Factors that Affect Radiosensitivity

  • Equivalent Dose
  • Effective Dose
  • Organ Sensitivity

Dose Response Curves

Linear No Threshold

Educational Objectives

At the completion of this program, participants will be able to:

  • Recall the direct and indirect damage that may occur as a result of radiation
  • Illustrate cell survival curves
  • The Law of B & T
  • Identify the structures of a Stochastic Dose response curve
  • Describe the Linear No Threshold model
