CCP Instruction For X-Ray Machine

Hi,

We recently purchased X-ray machine to detect foreign matters in baked cookies and which are aluminum foil wrapped. I need help with writing up the CCP work instruction for X-ray machine.

Another question is, X-ray machine can not detect aluminum due to low density. Should my product first pass through metal detector first  to control aluminum foreign matters and other metals like Fe and S.S and then through the X-ray machine at last to control foreign matters other than metals? If I put the x-ray machine as the last step on this cookie line after labelling, how do I justify auditor that I am controlling the aluminum foreign matter.

Thanks

hi, I worked with xray a few years back and we did infact have a metal detector first prior to x ray for this reason. We used the xray mainly for product count at this time though. I would risk asses the possibility of aluminium contamination and take it from there. however if you do have a metal detector not being used then it cant hurt to put it on the same line.
