Description

Surface pollution detector based on adjustable detection angle of body surface radian

Technical Field

The utility model relates to a surface contamination detector based on adjustable detection angle of body surface radian belongs to radiation monitoring and radiation and is infected with wounded's body surface pollution detection area, is applicable to the measurement that has natural radian body surface (like arm, leg) radioactivity to be infected with, also can be used to comparatively flat body surface pollution detection such as chest, back of the body.

Background

Nuclear explosion or nuclear accidents of nuclear weapons with uranium plutonium nuclide leakage are likely to cause the situation that the skin is infected by radioactive substances, and the skin can be continuously damaged if the skin is not treated in time. The surface contamination of the suspected contaminated site is detected in time, the contaminated site and the contamination amount are determined, and the contaminated skin is decontaminated according to the detection result.

The currently common methods and devices for detecting surface contamination by radioactive contamination on body surfaces mainly include the following:

1. direct measurement using a surface contamination detector (e.g., Como170, LB 124). The biggest disadvantage of this method is that the detection window of the surface contamination detector is horizontal, and can detect the relatively flat skin surface of the chest, back, etc., but the human body surface with natural curvature, such as limbs, neck, etc., is difficult to detect by using this method. The forced use of the method is likely to cause the surface pollution detection to be polluted by radioactive substances due to the fact that the skin is contacted too close, even if the skin is not contacted, only the part closest to the surface pollution detector can be detected due to the contradiction between the radian of the skin and the horizontal plane structure of the detection window of the surface pollution detector, and the radioactive contamination level of other parts is seriously underestimated or even cannot be detected.

2. An RDD-1 model systemic contamination detector was used. The device sets several surface pollution detectors into a string according to human natural radian, reduces single surface pollution detector detection area promptly, increases the quantity of detector to reach the purpose of laminating human natural radian. The defect is that the distances between the surface pollution detector and the parts of the head, the neck, the back, the hip and the legs cannot be consistent due to the fact that a human body is not horizontal from top to bottom, and measurement errors are artificially introduced into surface pollution detection data; when the detection distance is too far, the detection result has low reliability or even can not be trusted.

3. Hand and foot contamination monitors (e.g., HandFoot-FibreTM XL and HFC types) are used. The device has the greatest characteristic that the device is only suitable for detecting the radioactive contamination of hands and feet, but has no effect on other parts except the hands and the feet.
