  • Metal Objects Detection by X-Ray-Shadows

    This could be THE Breakthrough for metal detection at longer distances !!!
    And you are very lucky to get this info from me here and for free!


    The (My!) idea is the following:

    Everywhere in the world there is x-ray (and other very short wave directional) background radiation.
    Metal objects will block this more or less completely, like the bones on a x-ray roentgen picture.

    Now the question is:
    How high is the contrast if it comes to a larger distance and if buried in mineralized soil.

    I doubt a little golden ring buried 20cm in the ground will be detectable this way,
    but a large and thick metal object for shure.

    But some high definition x-ray camera with zoom (what kind of lenses do you use for x-rays??? )
    would be needed to show the "dark spots" which are probably metal-objects.

    Since zoom will be not an option the x-ray sensitive sensors must have 10 Megapixels
    or something like that for being able still seening very small buried metal objects.

    btw. the stupid LRL-lunatics never have written about this idea anywhere because
    they are just wanna fool around and are far away from realistic technology!
    This is my own idea and it is simple but genious and perhaps the only way ever
    for creating a real working long range detector!

    Because either the metal-object sends out by itself some radiation or it was
    turned on by some external energy to do that or it is passive and the surrounding
    energy built up some contrast factor which is working good enough for detection.

    Of course such a x-ray camera also would detect directly any radioactive objects!
    The average screen would be grey or green while the shadows are black or blue
    and the active energy radiating metal-objects white and shining or red.

    Well - meanwhile we can detect the for the eyes invisible infrared-radiation
    from remote-controls etc. with our digicams and handys but we are far away
    from cheap X-ray cameras! They would costs a huge amount of money!


    So whats the simple solution?

    A bundle of ion-chambers, very small and long so they are as directional as possible!
    7 such chambers bound together in a circle and each connected with an output.
    If the ion-tube in the middle gives a discriminated signal the user knows that the metal object
    is exactly at the pointed direction. Because the metal-object blocks the highly directional x-rays
    and therefore a weaker total signal will reach the tube.

    Of course the main challenge will be making the detector perfectly adjustable exactly to the
    very weak x-ray "background-noise". But we see it from the ultra-small digicam sensors
    which collects the light and colors for the images that it is possible. With ISO 3200 per instance
    a picture of a room can be made which receives its light by only one small candle.

    btw. this discovery means that any so far ion-chamber-equipped-LRL-detectors do not detect
    the metals ions but they are some sort of camouflaged directional geiger-counters!
    But for shure they will not detect a little golden ring from 10m distance because
    the x-ray-shadow is far to weak to get detected and the ring even has a hole.

    However x-rays are the only rays which are really useful for long rang metal-detection!
    As long as the metal objects do not produce heat by themselves like a shortcuted battery.
    But even then if buried the infrared-radiation would get blocked by the soil.

    And even x-rays do not travel through anything like a knife goes through butter!
    If the buried treasure lies very deep and the soil is mineralized or full of metalic-salts
    of course the x-rays also will become weakened.

    Anyway:
    Important is that the metal-object-shadow is clearly identifiable.

    Either the metal object is large and thick enough for this task or the detectors sensitivity is!


    Good luck and I warn you, damned LRL-liars! Don't fool around with this knowledge and
    betray the outside world with it! I made it public so everyone can experiment first hand
    with it or try to get it working!

    For being highly directional very long and very small ion-tubes connected to an extremely
    sensitive and highly adjustable and selective circuit will be needed. Don't forget this.

    Otherwise you will have just built yourself a simple x-ray meter!


    And the luxury version will be connected to a LCD screen or smartphone so even the
    slightest signal changes are visible and not just audible or seen by some blinking LED.

      I see some troubles with this design.

      1) I am afraid there is only small amount of x-ray you can catch. Mostly absorbed in atmosphere before it can reach surface of our planet.

      2) This radiation come from space. This technique will be very usefull on Jupiter, because Jupiter itself generates radioation and it can be absorbed by metal objects while it travel out of the planet. But Earth is too small to generate its own radiation.

      If it will work, you will need exposures in range of hours/days to get enought photons to make picture i think.


      Simpliest way to do this is dig a tunnel under place you want to search and place there source of radiation, then buy one of these - for sure extremely cheap High energy detectors http://www.andor.com/scientific-came...ergy-detection - then simply walk over it

        @ Hyena
        Thanx for the link. Direct X-Ray detection CCD - wow!
        here the pdf: http://www.andor.com/pdfs/specificat...ifications.pdf

        Let us install a very strong x-ray source at Australia which goes through the whole planet!



        But serious:
        The most simple metal objects to detect with such a x-ray camera would be the depleted uranium ammunition!
        Or radioactive parts at Chernobyl!

        Btw. I heard that meanwhile 15.000 US-soldiers have died from the aftereffects of the radioactive uranium dust!
        I have no proof if this is true but healthy for shure it isn't to breathe in those uranium-explosion-dust-clouds.

        Well, the main point will be the radiation contrast and how high it is.
        Pictures with a very long exposure-time can collect higher amounts of radiation.

        I'm sure that any metal object always will have a different strenght of very low x-ray self-radiation
        compared to the area where it can be found because the metal comes originally from a total different location.

        So either the metal-object will stop the x-rays which are coming from behind this object
        or the metal by itself will radiate a different amount of x-rays compared to the location where it is buried.

        However, the deeper the metal is buried and the lower those radioactive contrast-values are,
        the more sensitive the camera or detector has to be.

        But some not buried radioactive rock or metal-object would shine like a fire in the night and could
        get detected from even miles away with such a detector.

        It would be also an important part of demining activity in the future because all this radioactive
        ammunition remains or UXO for sure are not healthy for the children and people who live at
        ex-war-zones. And usual x-ray meters are not precise enough to find all this dirty crap.
