X ray machine operation and detection

Hi everyone!

I would like to get some information with regards to the operation and detection of an X ray machine.

1, What minimum size that an X ray machine can detect?

2. How does the x ray machine detect contaminant? its operation?

Thanks in advance for your help guys.

Hi Chebar

Im no where near a pro in X-Ray detection but o do have some experience. We did use one to detect foreign bodys in desserts and in very simple terms it bascially looked for diiferent shades of colour within each product. You would run a few products through it, it would x ray them so it could registar the common colour differences and then if it detected an unusual shade during the run i.e.a darker or lighter than what it expects to see, then  it would reject the product. Its exactly like when you break your leg and the break is a different colour to the rest of the bone. You can change how sensitive you want it to be if there is quite a varied difference when the product has been x rayed and therefore a large colour difference. To be quite honest we moved away from it as it was very tempremental and even the supplier couldnt get it to be robust enough to trust as in our particular case there could be quite a difference between each product.

From the point of how small will depend on how much you want to spend and how sensative your machine is. Remember in other industry's they are used to find hair line cracks whether in bone or even in the construction of sky scrapers.

Id ask myself whether its necessary to have one versus a metal check unless you have a likely hood of non metal contaminents in your products and in that case id look at issues earlier in your process before relying on an x ray
