A method based on the measurement of velocity of the fall of a ball containing a radioactive isotope, such as Co/sup 60/, Zn/sup 65/ or Sn/sup 113/ was used for determining the rheological prooerties of suspensions. Other isotopes may be also used, as long energy of their gamma radiation is more than 80 kev and they can be fabricated in the form of powder or wire. Activities of about 30 to 40 microcuries were used for labeling a single ball. The viscosity values agreed quite well with control tests performed with a rotating cup viscometer. A scintillation counter and a photomultiplier tube were used for determining the location of the ball. The optimum depth for the radiation collimator was calculated at about 62% of the vertical path of the fall of the ball. (TTT)
