Geant4. Welcome to the CRÈME site — CREME-MC site. Lesson 3. Advances in Space Research - A review of instruments and methods for dosimetry in space. Abstract Instruments and methods recently used for space radiation dosimetry are reviewed for the purposes of comparison and reference.
Passive detection methods mentioned include track-etch, luminescent, nuclear emulsion, and metal foil detectors. How is the 'STERADIAN' defined and how is it used? How is the 'STERADIAN' defined and how is it used?
Asked by: Undisclosed Visitor Answer Steradians are a measure of the angular 'area' subtended by a two dimensional surface about the origin in three dimensional space, just as a radian is a measure of the angle subtended by a one dimensional line about the origin in two dimensional (plane) space. Steradians are equivalently referred to as 'square radians.'
