Title:
RADIATION AND ION DETECTION DEVICE EQUIPPED WITH CORRECTION DEVICE AND ANALYSIS DISPLAY DEVICE AND ANALYSIS DISPLAY METHOD
Document Type and Number:
WIPO Patent Application WO/2013/057803
Kind Code:
A1
Abstract:
[Problem] To provide, although it is generally difficult to detect radioactive materials present in a material, a technique for detecting the radioactive materials.
[Solution] When radiation travels inside a material, the material is ionized, in which part of the ionized material is recombined and the remaining ionized material is polarized on the surface of the material.
Therefore, it is possible to know an ionized state in the material by using an analysis display device (4) or a correction analysis display device (5) in such a way that: a voltage is applied to a dielectric counter tube (1) including a thin film dielectric material used in a detection portion of the dielectric counter tube to more strongly electrically induce ionized matter that is present and to detect a resulting small potential difference; and the potential difference is amplified by an amplifier (2) and corrected according to the temperature by a correction device (3) or a thermometer (6). In addition, although being weak, each type of radiation can also be directly detected. It cannot be determined that being in an ionized state is always caused by radiations, but in a material that cannot be normally ionized, it can be said that an abnormality is occurring. Since an ionized state in a material is known, it also becomes possible to determine the presence or absence of tumor, pain in an affected area of human, and the like.
