1. A method of determining the relative concentration of a material in a turbid medium which comprises:

  • shining light through said turbid medium;

    determining the scattering coefficient of said turbid medium using said light that has passed through the turbid medium;

    comparing said scattering coefficient with a previous scattering coefficient of said turbid medium, whereby a change in said scattering coefficient indicates a change in the relative concentration of said material; and

    determining said relative concentration from said scattering coefficients.
