DEFINITION

Classification: 436/57

INCLUDING USE OF RADIOACTIVE PROPERTIES:

(under the class definition) Processes or compositions wherein analysis or a chemical reaction includes measurement of radioactivity.

(1) Note. This subclass includes scintillation counting and sample preparation by pyrolysis or combustion.

516, Colloid Systems and Wetting Agents; Subcombinations Thereof; Processes of Making, Stabilizing, Breaking, or Inhibiting, appropriate subclasses for subject matter relating to: colloid systems (such as sols*, emulsions, dispersions, foams, aerosols, smokes, gels, or pastes) or wetting agents (such as leveling, penetrating, or spreading); subcombination compositions of colloid systems containing at

least an agent specialized and designed for or peculiar to use in making or stabilizing colloid systems; compositions and subcombination compositions specialized and designed for or peculiar to use in breaking (resolving) or inhibiting colloid systems; processes of making the compositions or systems of the class; processes of breaking (resolving) or inhibiting colloid systems; in each instance, when generically claimed or there is no art class. Class 516 provides for compositions otherwise seemingly proper for Class 436 when the compositions are colloid systems or wetting agents.

600, Surgery, 407+, for methods for detecting radiation emanating from a radioactive material in the body.
