SUMMARY
The calculation of absorbed dose in mixed liquid phantoms from X-ray machines involves using the formula: Dose phantom = Dose air x (mSwall / mSair) x (mass absorption coefficient phantom / mass absorption coefficient of wall material). To determine the absorption coefficient for a liquid mixture, one must consider the mass proportions of each component, such as salt and water, and apply their respective absorption coefficients. For polymer solutions, the percentages of monomers and water must be accounted for in the calculations. The use of an electrometer to measure charge is essential for substituting values into the formula to find the absorbed dose accurately.
