Abstract: A method for causing an isomeric change from a radioactive isotope to an other isotope having a lower energy state relative to said radioactive isotope. The method includes irradiating a sample that includes the radioactive isotope with a gamma or x-ray beam having photon energy ranging from 10 eV to 10 MeV for a time sufficient to stimulate the release of extra energy in the form of photons from the sample, and convert at least a portion of the radioactive isotope in the sample to the other isotope.

Abstract: A method for reducing radioactivity in a radioactive sample is disclosed, comprising contacting said sample with a beam of photons, said beam having an energy level sufficient to cause said radioactive sample to emit particles including photons in an amount sufficient to accelerate a reduction in radioactivity of said sample. Also disclosed is a method of increasing radioactive decay in a radioactive isotope comprising the steps of: determining a beam of an effective energy and effective flux of photons to increase radioactive decay in the radioactive isotope; applying the beam to the radioactive isotope; and maintaining the beam for an amount of time effective to increase the radioactivity of the radioactive isotope.

Abstract: A filling and weighing system and method for particulate matter in which the particulate matter in powder form is electrically charged and electrically directed to a container on a weight-frequency sensitive balance. The frequency shift of the balance is a measure of the weight of the powder in the container and when a predetermined frequency shift occurs, this is a measure of a predetermined weight of the powder in the container.
