Chapter 20, Problem 59QP
Interpretation Introduction
Interpretation:
Rad andrem, and their relation, areto be explained.
Concept introduction:
Rad is a unit used to measure the energy absorbed by an object.
Rad is the unit of the absorbed dose of radiation and is defined as the measure of the radiation that comes from the absorption of
Rem is used to measure the energy absorbed by a human being.
Rem is the unit of radiation dosage that is applied to human beings. It is the Roentgen equivalent for man and is calculated with the help of the biological effect of radiation.
The relationship between rad and rem is expressed as:
