In order to investigate the anomalous heat effect (AHE) in NiCu multilayer thin film, photon radiation calorimetry has been developed. Three types of photon detectors are employed to cover a wide range of wavelengths from 0.3 um to 5.5 um, i.e., photon energies from 0.2 to 1.8 eV. In the present work, the usefullness of the calorimetry is demonstrated for excess heat measurements with samples of Ni pure, NiCu composite layers, and Cu layer deposited on the Ni substrate. Direct comparisons of photon radiation spectra with and without H2 easily showed sample-specific differences in excess heat power. The samples of NiCu composite layer produced larger excess heat. By incorporating the measured radiant power into a heat flow model, the excess heat was deduced to be 4 - 6 W. The energy generated in 80 hours reached to 460 +/- 120 kJ: the generated energy per hydrogen was at least 410 +/- 108 keV/H atom. This is definitely not a chemical reaction, but producing energy at the level of nuclear reactions.
