NANTeL Radiation Worker Training Practice Test

Whole-body dose is described by TEDE, the Total Effective Dose Equivalent. This dose metric represents the overall risk to the entire body from radiation exposure by combining the energy absorbed with how different tissues respond to radiation and the type of radiation involved. It provides a single value that reflects the potential biological impact of external and internal exposures on the whole body. The other terms refer to types of radiation—beta particles, gamma rays, and neutrons—which describe the nature of the radiation rather than a measure of the body-wide dose.
