Abstract: A method for removing silica from an aqueous solution is provided. The method includes steps of flowing the aqueous solution into an electro-Fenton reactor, wherein the reactor comprises one or more electrodes in a bipolar arrangement positioned between a monopolar iron anode and a monopolar cathode; applying an electric current to the aqueous solution such that silica aggregates form on ferric hydroxide; and removing the silica aggregates from the aqueous solution.

Abstract: Neutron dosimetry is performed using a water-based chemical dosimeter measurement of radiation-induced reduction of hexavalent Cr (VI) to trivalent Cr (III) in the presence of sodium formate at pH 9.2. Neutron absorbance material (Gd-157) increases the neutron interaction with the dosimeter. When a monoenergetic beam with 0.025 eV energy was used as a thermal neutron source 1 mol/dm3 of Gadolinium gave the best outcome while surrounding the dosimeter with 1 cm Gadolinium sheets. The dosimeter was giving acceptable readings when using thermal neutrons.

Abstract: An Actinium-225 generator is provided. The generator includes a neutron source; a neutron target arranged to receive neutrons emitted from the neutron source, wherein the neutron target comprises nickel; and a proton target arranged to receive protons emitted from the neutron target, wherein the proton target comprises radium-226. Methods for producing Actinium-225 are also provided.

Abstract: A method of determining the radiation doses to which specific locations are subjected is provided. The method comprises providing an assembly comprising a plurality of layers, each of which includes a number of regularly spaced individual compartments that contain a liquid that changes in color when exposed to radiation, radiating the assembly, determining the changes in optical density of the liquid in the individual compartments and calculating the doses of radiation to which the compartments have been subjected from the changes in optical density.
