  • Gel dosimeter for measuring radiation dosage and manufacturing method therefor
    Patent number: 9213105
    Abstract: To measure three-dimensional dose distributions with a dosimeter, such as a gel dosimeter. In an embodiment of the present invention, provided is a gel dosimeter having water, as solvent or disperse medium, clay particles that swell with water, and recording material precursor, which are dissolved or dispersed with each other. The recording material precursor has an atom or ion, wherein the atom or ion changes its valence number by reacting with both of a radical and a molecular radical derivative. The radical is to be generated from the water ionized by irradiation of radiation rays, and the molecular radical derivative is a molecule to be formed by bonding the radicals with each other. By the time radiation rays are irradiated, the gel dosimeter has been free from a substance identical to the molecular radical derivative and has lost fluidity.

  • Method of constructing chimeric plant by heavy-ion beam irradiation
    Patent number: 7851771
    Abstract: Petunia explants are irradiated with heavy-ion beams, and the chimeric individuals differentiated from the explants are selected (FSRP method). Then, explants are obtained from the chimeric individuals and subjected to tissue culture, followed by selection of re-differentiated chimeric individuals with stable characters (SSRP method). By these procedures, it becomes possible to create chimeric plants such as variegated petunia efficiently.
