For single plane implants with gold seeds, assuming a matrix distribution for the seeds, the optimum separation of the matrix elements and the optimum ratio of the activity of the seeds in the area to that of those in the periphery were calculated, so that the uniformity of dose distribution is within plus or minus 10%. Area dosages were also computed and are tabulated. The dose variations in double plane implants and volume implants also were studied and the results are presented. Dosage graphs are given for both cases. The theoretical dose distributions were verified for a few implants experimentally using LiF thermoluminescence dosimeters. (auth)
