[ RadSafe ] Linear attenuation coefficient for biological ashes

[Dixon, John E. (CDC/ONDIEH/NCEH)]

Lidia,

If you can determine the elemental composition using X-ray spectroscopy, you could calculate the coefficient for each sample. X-ray spec could give you what is in the sample, but not what the sample "looks like" inside.

Regards,
John Dixon

Subject: [ RadSafe ] Linear attenuation coefficient for biological ashes

Dear all,

I am looking for the linear attenuation coefficient of X-rays in ashes. I checked the NIST database http://physics.nist.gov/PhysRefData/XrayMassCoef/tab4.html , but there is no such material included.

Does anyone have a suggestion of where to find data for biological ashes?

Rgds
