Using a small silicon diode and the Therados RFA-3 automated dosimetry system, the relative dose distribution around Fletcher-Suit-Delcos colpostats was measured. Thermoluminescent dosimeters (LiF) were used for absorbed dose measurements. These data provide the basis for computerized dose calculations which will account for the attenuation effects of the rectal and bladder shieldings. The stainless-steel housing attenuated the radiation of a Cs-137 source by 6%. The tungsten shields caused a further dose reduction of 15%-25%.
