Abstract
A method and apparatus for estimating a heating value of a biological material. The method includes irradiating of the biological material with X-ray radiation of at least two different energy levels, measuring of an amount of radiation transmitted through the biological material at these energy levels, and measuring fluorescent radiation emitted by the biological material when irradiated at these energy levels. A final estimate of the heating value is then determined based on a preliminary estimate of the heating value of the biological material based on the measured transmitted radiation and a correction value based on the fluorescent radiation.

A method for estimating a heating value of a biological material, comprising:
- irradiating the biological material with X-ray radiation of at least two different energy levels;
- measuring an amount of X-ray radiation transmitted through said biological material at said at least two different energy levels;
- measuring fluorescent X-ray radiation emitted by the biological material when irradiated at said at least two different energy levels;
- and
- determining a final estimate of the heating value of said biological material, based on a preliminary estimate of the heating value of said biological material, wherein said preliminary estimate is based on said measured transmitted X-ray radiation, and a correction value, based on said measured fluorescent X-ray radiation.
An apparatus for estimating a heating value of a biological material, comprising:
- an X-ray radiation source for irradiation of a biological material with X-ray radiation of at least two different energy levels;
- a detector for receiving X-ray radiation transmitted through said biological material, said detector determining, for each energy level, the amount of X-ray radiation transmitted through the biological material;
- a fluorescence detector for measuring fluorescent X-ray radiation emitted by the biological material when irradiated at said at least two different energy levels;
- and
- a controller arranged to determine a final estimate of the heating value of said biological material based on a preliminary estimate of the heating value of said biological material, wherein said preliminary estimate is based on said measured transmitted X-ray radiation, and a correction value, based on said measured fluorescent X-ray radiation.
