The article describes a mathematical model of photon transport and generating the secondary electromagnetic fields in structures of complex geometry and package. A draft of the model design is given. The results of computing the photon flux in different elements of the model structure are demonstrated. It is shown that multiple-material stack-up of the enclosure can dramatically weaken the photon flux, scattering not only soft but hard photons as well. Intensity of absorption has pronounced maxima. There is space charge and the electrostatic field generated in the gas atmosphere inside the model. Electrostatic field can reach high amplitude in a small spatial domain inside the enclosure of the model.
