  • Method and apparatus for preparing Bi-213 for human therapeutic use
    Patent number: 6485695
    Abstract: This invention relates to a method and an apparatus for preparing Bi-213 to be integrated in a radioimmunocojugate for human therapeutic use. According to the invention the method comprises the sequence of steps as follows: a) an ampoule 5 containing colloid-free actinium-225, obtained from drying an actinium nitrate solution, is loaded into a container 20 provided with radiation panels 21; b) a dissolving medium is poured into the ampoule 5; c) the solution obtained in the ampoule is transferred into an ion exchange column 6; d) an elution medium is circulated through the column 6; e) the eluate containing eluted Bi-213 is pumped towards a vial 10 for quantification and quality control.

  • Method for producing Ac-225 by irradiation of Ra-226 with protons
    Patent number: 6299666
    Abstract: This invention refers to a method for producing Actinium-225, comprising the steps of preparing a target (1) containing Radium-226, of irradiating this target with protons in a cyclotron and of chemically separating Actinium from the irradiated target material thereafter. According to the invention the proton energy in the cyclotron is adjusted such that the energy incident on the Ra-226 is between 10 and 20 MeV, preferably between 9 14 and 17 MeV. By this means the yield of production of the desired isotope Ac-225 is enhanced with respect to other radioisotopes.

  • Method for the destruction of plutonium by irradiation in a light water reactor
    Patent number: 5966418
    Abstract: This invention relates to a method for the destruction of plutonium (Pu) by irradiation in a light water reactor (LWR). According to the invention Pu is mixed with highly enriched uranium (U) in roughly equal weight proportion rates. This mixture is embedded in an inert matrix of a material whose components have an atomic number significantly lower than 92. LWR fuel pins are then produced therefrom and these pins are inserted in a LWR in place of certain normal LWR fuel pins. The irradiation time of the fuel pins containing Pu is significantly longer than that of said normal pins. The irradiation is preferably repeated after about 200 years without any reprocessing of the spent fuel.
