ABSTRACT:
A method of radiation measurements on slurries where the slurry is pumped to a pressure where the volume of gases in the form of gas-bubbles is reduced below a level where the gases effect the radiation counts. The slurry pressure is raised to a pressure in the range of 100 p.s.i. to 500 p.s.i. (690 kPa to 3.5 Mpa) absolute using a positive displacement pump.
