Since energy absorption seemed to be related to biological response, it was natural to define absorbed dose. Absorbed dose due to any ionizing radiation is the energy imparted to matter by ionizing particles per unit mass of irradiated material at the place of interest. The unit of absorbed dose is the "rad" and is equal to an energy absorption of 100 ergs/g. R A D I A T I O N FIELDS 37 Most portable survey instruments for electromagnetic radiation depend for their operation on the measurement of ionization produced in air or other gas, and are usually either ionization chamber or Geiger-Muller tube instru­ ments.
