Re: X-ray's light testing

Is this inquiry about scanning electron microscopes (SEMs)? The posted link provides calibration resources for SEMs.

If the question instead was about medical-diagnostic Xray equipment, are calibration instruments for SEMs considered acceptable for medical-equipment calibration? The technology is very different, and I'm under the impression that the instrument-calibration-chain requirements for medical calibration are rigorous.

It would help if the original poster could more fully explain what equipment and application they're asking about.

Perhaps these will help:

http://www-naweb.iaea.org/nahu/dmrp/...nqualities.asp

Maybe that will help?

Have a look at FDA's 21 CFR Part 1020.30 referring to the PERFORMANCE STANDARDS FOR IONIZING RADIATION EMITTING PRODUCTS and Sec. 1020.30 Diagnostic x-ray systems and their major components.

Re: X-ray's light testing

Take a look at this also - AAPM Report No. 31 - STANDARDIZED METHODS FOR MEASURING DIAGNOSTIC X-RAY EXPOSURES which is Published by the American Association of Physicists in Medicine by the American Institute of Physics.

Sorry I do not know about any ISO standard

Re: X-ray's light testing - What is the standard to test the X-ray light brightness?

hI mateS,

Oops... misleading information given! ...

actually I am looking for the testing relevant to X-ray scanner's light testing BUT NOT the X-ray radiation. Is there any testing or specification for that light as specified in any national or international requirements?

Anyone there can help me??

looking forward.....
