Absorbed dose calorimetry: bridge nulling and voltage analysis techniques.
A theoretical analysis is made of the conventional calorimeter approach utilizing a two-thermistor Wheatstone bridge--an approach which requires balancing the bridge by adjusting variable resistances. However, with the current availability of computers and digital precision measuring instruments, the conventional calorimeter approach can now be readily replaced by an automated, nonmechanical, electrical systems approach called differential calorimetry. The analytical theory outlining such an approach is also presented.
