Abstract
Experimental measurements in a water phantom were made for a new shielded plastic Fletcher applicator. A dose calculation algorithm which allows the description of asymmetrically shielded source containers is presented. The traditional primary plus build-up factor description of the dose in a homogeneous volume is corrected by using effective attenuation coefficients measured in a water phantom for all the source-shield-container materials. Comparison of the theoretical results to the experimental data shows excellent agreement.
