  • Color indicator-dosimeter of ionizing radiation
    Patent number: 4001587
    Abstract: The color indicator-dosimeter of ionizing radiation in accordance with the invention comprises 70 to 100 parts by weight of a thermoplastic polymer, 10 to 40 parts by weight of a plasticizer, 0.5 to 3.0 parts by weight of a stabilizer and two dyes compatible with said polymer. One of said dyes is incorporated in the color indicator-dosimeter to the extent of from 0.007 to 0.01 part by weight; its G value of decolorization in the polymer is 0.05 to 0.1 molecule/100 eV and its absorption maximum lies in the 450 to 590 nm spectral range. The other of said two dyes is incorporated in the color indicator-dosimeter to the extent of from 0.015 to 0.03 part by weight; its G value of decolorization in the polymer is 0.15 to 1.5 molecule/100 eV and its absorption maximum lies in the 600 to 720 nm spectral range.The proposed color indicator-dosimeter of ionizing radiation permits measuring dose rates in the range from 0.5 .times. 10.sup.6 to 3.5 .times. 10.sup.7 rad to within .+-.
