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 containing colloid-free actinium-225, obtained from drying an actinium nitrate solution, is loaded into a container provided with radiation panels ; b) a dissolving medium is poured into the ampoule ; c) the solution obtained in the ampoule is transferred into an ion exchange column ; d) an elution medium is circulated through the column ; e) the eluate containing eluted Bi-213 is pumped towards a vial for quantification and quality control.

Method and apparatus for preparing Bi-213 for human therapeutic use

Described are a process and an apparatus for the remote measurement of uranium or plutonium in radioactive materials. in which the sample of the material to be analyzed is to be handled as little as possible. To attain that object it is proposed that the laser beam of a laser is focussed by means of a focussing unit onto the sample to be analyzed, so that a light-emitting plasma is generated, an image of the emission spectrum of the plasma is formed in a spectrograph by means of an imaging unit, and finally it is analyzed by means of an analyzing unit.

This invention refers to a method for producing Actinium-225, comprising the steps of preparing a target (,) 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.
