<p>A method for estimating a heating value of a biological material is disclosed. The method comprises: correlating amounts of radiation transmitted through a number of different reference materials, said radiation being electromagnetic radiation of at least two energy levels, with heating values for said reference materials obtained by calorimeter measurements; irradiating the biological material (102) with electromagnetic radiation of said at least two different energy levels; and measuring the amount of radiation (109a-c) transmitted through said biological material at said energy levels. The method further comprises determining, for each energy level, a transmission value through the biological material based on the radiation through said biological material; and determining, based on said determined transmission values and said correlation, an estimate of the heating value of said biological material. A corresponding apparatus (100) is also disclosed.</p> |
