Abstract
The determination of absorbed dose in an organ is of critical importance especially in medical therapy applications. In this study the total attenuation coefficient has been measured experimentally and absolute activity has been calculated using an application of a general method presented by Fleming. The absorbed dose for different distances from the source has been determined using absolute activity with using Perspex phantom. The true dose value given to the medium has been investigated and the results were discussed.
Key words: Absolute activity, absorbed dose, g-rays, attenuation coefficient.
