Physics. the process in which energy is emitted as particles or waves. the complete process in which energy is emitted by one body, transmitted through an intervening medium or space, and absorbed by another body. the energy transferred by these processes. ...
Since cosmic rays contain information on the behaviour of matter in the smallest (elementary particles) and largest dimensions (the universe), they have been particularly valuable in testing the concepts of daily life in relation to their meaning in physics and in leading physicists to find new ...
The meaning of PLANCK RADIATION LAW is a law in physics: radiant energy arising from processes within atoms or molecules is emitted in finite quanta each of which is equal to the product of the radiation frequency by a universal constant h.

The unit of exposure is measured in roentgens (R). The exposure is defined strictly for air as the interacting medium. There is a way to quantify different radiologic procedures called the “entrance skin exposure,” meaning the exposure at the location in space where the central beam of ...
Similar to non-ionizing radiation, ionizing radiation is energy in the form of particles or waves. However, ionizing radiation is so high in energy it can break chemical bonds -- meaning it can charge (or ionize) an atom that interacts with it. At a lower energy, it may strip off a co...
