Abstract:
1. A method of irradiating a material in an elution capsule, the elution capsule including, a tube with a first end portion having a first inside diameter, a second end portion having a second inside diameter, a singular first opening in the first end portion and a singular second opening in the second end portion, the first and second openings facing opposing directions and being about collinear with a longitudinal centerline of the tube, a middle portion having an inside diameter smaller than the inside diameters of the first and second end portions, the middle portion being between the first end portion and configured to hold the material, an interface between the first end portion and the middle portion forms a first shoulder and an interface between the second end portion and the middle portion forms a second shoulder, a first washer inside the first end portion contacting the first shoulder, a first filter inside the first end portion contacting the first washer, a second filter inside the first end portion contacting the first filter, the first filter being located between the first washer and the second filter, a first end cap sealing the first opening, a second washer inside the second end portion contacting the second shoulder, a third filter inside the second end portion contacting the second washer, a fourth filter inside the second end portion contacting the third filter, the third filter being located between the second washer and the fourth filter, and a second end cap sealing the second opening, the method comprising: placing the material in the middle portion of the elution capsule; placing the elution capsule in a neutron flux source; and irradiating the capsule and the material in the neutron flux source.
