Permanent and removable interstitial implantation techniques for neoplasm radiotherapy using absorbable and unabsorbable sutures are described. Most of these techniques can be performed in the clinic easily and quickly with basic instruments: needle holder, needle book, and hemoclips. Specifically, $sup 192$Ir (74.4 day half life, 300 to 610 keV, and 6.0 cm hvl in tissue) nylon ribbon and $sup 125$I (60 day half life, 27 to 35 keV, and 2.0 cm hvl in tissue) Vicryl sutures are described. A major advantage of the $sup 125$I over the $sup 192$Ir seed (other than the fact that it can be permanently implanted and needs less radiation protection) is that the patient does not remain highly radioactive for as long a period due to the extremely low $sup 125$I energy and may be allowed to leave the hospital. Both nuclides have the advantage of a long shelf life, making their use practical and economically feasible. (auth)
