INTRODUCTION Radiation‚ flow of atomic and subatomic particles and of waves‚ such as those that characterize heat rays‚ light rays‚ and X rays. All matter is constantly bombarded with radiation of both types from cosmic and terrestrial sources. This article delineates the properties and behaviour of radiation and the matter with which it interacts and describes how energy is transferred from radiation to its surroundings. Considerable attention is devoted to the consequences of such an energy
