A simple gel-to-gel method is described for the estimation of diffusion coefficients (D) of radio-isotopic chemicals. "Cold" and "hot" gel cylinders, enclosed in small hypodermic syringes with their needle ends cut off, were carefully joined together, and diffusion was allowed to proceed for several hours. Slices of gels were then obtained for counting of activities. Application of the classical theory of diffusion permitted calculations of D values.
