About this Program

This program will review the differences between deterministic and stochastic radiation effects. Specific signs and symptoms of radiation injury will be detailed, along with a discussion about the importance of communicating risks with patients.



How much Radiation is Safe?

Avoiding Deterministic Thresholds

  • Severity depends on Dose

Stochastic Risk from Low Level Radiation

  • Not does dependent

Risks to Embryo/fetus in Utero

  • Radiation Risks
  • Stages of Gestation

Background Radiation & Everyday Risks

  • Cosmic
  • Terrestrial

Communicating Risk to Patients & Colleagues

  • Compare to Everyday Background Radiation

Educational Objectives

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

  • Recall the skin erythema threshold
  • Express the annual background radiation
  • Define the latency period for leukemia and solid tumors
  • Discuss absolute vs. relative risk models
  • Differentiate stochastic response curves for high and low rate radiation
