Are you saying calorimeter measurements can measure sunlilght, UV and soft > X-Rays? I didn't think that was the case. Any electromagnetic radiation at these energies that is stopped within the volume of the calorimeter will be thermalized and picked up as a temperature increase. As others have mentioned, UV and soft x-rays do not have a long mean-free path in many substances and are likely to be stopped; if not within the calorimeter volume, then at its inner wall, unless the energy is primarily delivered as visible light and the calorimeter has a transparent wall. http://upload.wikimedia.org/wikipedia/commons/1/13/Attenuation.svg http://www.britannica.com/EBchecked/topic/613529/ultraviolet-radiation That a calorimeter is likely to pick up the energy delivered by such radiation is a detail that Mills will readily understand. Are you familiar with the details of the calorimetry, e.g., what kind of calorimeter was used? Eric
