Abstract: The present invention describes a membrane mask for immobilization of a region of interest during radiation therapy. The mask comprises at least one material forming a matrix, and at least one radiation-sensitive material integrated as micro- or nano-sized material elements in or onto the matrix. The radiation-sensitive material advantageously provides the possibility of using the mask for performing dosimetry. Use of the mask and a method for performing dosimetry also are described.

Abstract: A method for purifying Ac from a mixture includes Ac and at least one element selected from Ra, Pb, Po, Bi and La. The method includes the steps of: (a) performing a first separation using a first extraction chromatographic column based on a first resin (either a diglycolamide resin or a dialkylphosphoric acid resin) and a first matrix solution; and (b) performing a second separation using a second extraction chromatographic column based on a second resin (respectively either a dialkylphosphoric acid resin or a diglycolamide resin).

Abstract: A method for producing Pb-212 and Ac-225 isotopes is disclosed. The method comprises irradiating a Ra-226 containing target with charged particles and/or photons for producing at least Ac-225 isotopes and Ac-224 isotopes. The method further comprises after a cooling time, applying chromatography for separating actinium from the remaining fraction containing radium. The method also comprises, after a first further waiting time, applying extraction chromatography using a resin having an 18-crown-6 ether or an equivalent of an 18-crown-6 ether, as extractant in HNO3 and/or HCl for separating Pb from the remaining fraction containing radium.

Abstract: A system for measuring mechanical strain comprises a main spring and a connecting piece both with an open concave cross-section, the connecting piece is rotatable mountable inside the main spring at a fixing point, such that the respective open concave cross-sections are in the same plane and the open parts are oriented in the same direction. The legs of the main spring are connectable with the specimen shoulders for applying the tips of the measuring arms onto the gauge length of the specimen. Measuring arms are rotatably mountable on the legs of the connecting piece so as to push against the specimen when mounted and so as to rotate when the measured object is subject to strain.
