The classes of radioisotope applications are discussed. The scope of the requirements for special facilities are indicated and the facilities available at the Ford laboratory are briefly described.
A brief summary of the special techniques used for making radioactive Piston Ring Rotation, Air Flow, Gasket Leakage and Oil Mixing Measurements is given. Some other applications attempted by the Ford Laboratory are enumerated. Four general categories of isotope applications which should come into wide spread usage are described.
