  • Patent number: 11232878
    Abstract: A chemical decontamination method includes a dissolution step in which a radioactive insoluble substance containing a metal oxide, the radioactive insoluble substance being adhered to a decontamination object including carbon steel, is dissolved in a decontamination solution and a metal-ion removal step in which the decontamination solution containing the metal ion, the decontamination solution being produced in the dissolution step, is brought into contact with a cation-exchange resin in order to remove the metal ion, the dissolution step including a reductive dissolution step conducted using a decontamination solution containing formic acid, ascorbic acid and/or erythorbic acid, and a corrosion inhibitor.
    Type: Grant

  • Patent number: 7198908
    Abstract: To determine the transplant compatibility of an in vitro cultured tissue, a method measures the stiffness of the cultured tissue by using a stiffness measuring device, which stiffness measuring device includes a detecting unit and calculation means, the detecting unit includes a contact unit, a vibrator connected to the contact unit, and a vibration detecting unit for detecting the vibration of the vibrator, and the calculation means determines stiffness information by calculation based on the detected result from the vibration detecting element; and by bringing the contact unit into contact with the cultured tissue. With this method the transplant compatibility of the cultured tissue can be nondestructively and easily determined easily and the quality of the cultured tissue can be appropriately controlled.
