Hj production on solid materials is indeed a particular case of energy redistribution in a multiphase system, which is sometimes also referred to as radiation catalysis the energy of ionising radiation absorbed in one phase can be delivered to the interface and can induce physical and chemical processes in the other phase. 

The results showed that production of latices by radiation catalysis is a commercially feasible process. However, the authors did not appear to have resolved two process-development problems the reduction of residual monomer to commercially acceptable levels and the elimination of polymer build-up inside the process lines. Tbe authors noted, however, that these are problems of formulation and operation rather than of tbe basic process itself. 

In the theoretical part of this essay, energy degradation processes in solid are first considered. The conclusions drawn in this way allow us to propose a scheme of interpretation for the results obtained in the field of radiation catalysis and to establish a set of previsions, which are to be considered as work hypotheses and may eventually be used for establishing a more general theory. 

These are very important facts because they clearly show the effects of radiation catalysis to be essentially variable. The course of the reaction is not always influenced in a favorable way and in some instances a real inhibition may even occur. 

This subsection summarizes some results of radiation catalysis obtained in other laboratories. It is not our purpose to make a complete survey of the corresponding literature, but we want to mention these characteristic results, which may prove valuable for the subsequent discussion. 

The energy transfer from an irradiated sohd towards the gaseous phase, which can result in a modification of the thermodynamical equilibrium of the considered system, clearly distinguishes this aspect of the radiation catalysis from the activation process. This transfer phenomenon is related...
