radiation scattering

Radiation scattering is the deflection of radiation (electromagnetic or products of nuclear decay) from its original path as a result of interaction or collisions with atoms, molecules, or larger particles in the atmosphere or other media between the source of radiation and an observation point some distance away.

The diversion of radiation (thermal, electromagnetic, or nuclear) from its original path as a result of interaction or collisions with atoms, molecules, or larger particles in the atmosphere or other media between the source of radiation (e.g., a nuclear explosion) and a point some distance away. As a result of scattering, radiation (especially gamma rays and neutrons) will be received at such a point from many directions instead of only from the direction of the source. [JP1]

Déviation du rayonnement (thermique, électromagnétique ou nucléaire) de sa direction d'origine, causée par l'interaction ou la rencontre d'atomes, de molécules ou de plus grosses particules, dans l'atmosphère ou autres milieux, entre la source du rayonnement (par exemple une explosion nucléaire) et un point qui en est éloigné. En conséquence de cette diffusion, le rayonnement (en particulier les rayons gamma et les neutrons) sera reçu à ce point particulier en provenance de plusieurs directions au lieu de la seule direction d'origine. 1/11/68
