PA exposure dose during the seed-aligning process
PL exposure dose from the applicator in which a seed is loaded and already implanted seeds in the patient during the implantation process
PH exposure dose during the seed implantation to the patient which is estimated from the traditional process
PI exposure dose during the implantation process (PL+PH)
TL exposure dose during the traditional seed-loading process
TI exposure dose from the handling applicator, implanted seeds and prepared applicators beside the doctor during the traditional implantation process
