。゛ In Fig. 1, a shows a cross-sectional view of the center of a conventional cable in the longitudinal direction, and b shows a cross-sectional view of the same cable. Figures 2 to 5 show examples of cables with color dosimeters according to the present invention, in which figure a shows a cross-sectional view of the central part in the longitudinal direction of the cable, and figure b shows a cross-sectional view of the same cable. Figure 2 shows an example of a color dosimeter inserted into the entire insulator, and Figure 3 shows an example of one part of the insulator.
Figure 4 shows an example in which a color dosimeter is inserted into the surface of the insulator, Figure 5 shows an example in which a color dosimeter is inserted in a part of the surface of the insulator. . 1: Core wire, 20: Cable, 21: Insulator with colored dose needle, 30: Cable, 31: Insulator, 32: Color dosimeter, 40: Cable, 41: Insulator, 42': Insulator, 50: Cable, 51: Insulator, 52: Color dosimeter.

Claims

[Scope of utility model registration request]

comprising a color dosimeter inserted into part or all of the insulation of a cable used in a high radiation location;
A cable with a color dosimeter, characterized in that the degree of deterioration of the cable is determined by measuring the amount of radiation irradiated based on a change in color of the color dosimeter.
