What does the unit of equivalent dose take into account of?
Different biological effects caused by different types of radiation
Rad x Wr = ?
Equivalent dose (Rem)
Radiation weighting factor (Wr) is used to do what?
Modify the absorbed dose amount to account for the greater damage inflicted by some forms of ionizing radiation
