  • Method for removing metallic seeds from nylon tubing used in interstitial brachytherapy
    Patent number: 4190461
    Abstract: Described herein is a method for removing radioactive metal seeds from embedment in nylon. Nylon is added to a solvent to form a mixture comprising dissolved and undissolved nylon, solvent, and metallic seeds and the mixture is subjected to ultrasonic waves to substantially completely dissolve the nylon in the solvent, thus freeing up the metallic seeds. The solvent is decanted and the foregoing steps are repeated followed by adding acetone and decanting all resulting liquid. Finally the seeds are dried.
