Webradiation exposure unit: 1 roentgen = 1 R = 2.58×10−4 coulomb per kilogram. Thus, 1 R of radiation produces 2.58×10−4 C of positive ions in a kilogram of air at standard temperature and pressure, and an equal charge of negative ions. Radiation safety standards are expressed in units of roentgen equivalent mammal per year (rem/yr). WebSep 12, 2024 · In Equation 6.4.1, E is the total energy of a particle, p is its linear momentum, and m 0 is its rest mass. For a photon, we simply set m 0 = 0 in Equation 6.4.1, which leads to the expression for the momentum p f of a photon (6.4.2) p f = E f c.

WebCompton assumed that the incident X-ray radiation is a stream of photons. An incoming photon in this stream collides with a valence electron in the graphite target. In the course of this collision, the incoming photon transfers some part of its energy and momentum to the target electron and leaves the scene as a scattered photon. WebThe Stefan-Boltzmann equation then gives the energy flux emitted at the sun’s surface. S S = (5.67 × 10 –8 W·m –2 ·K –4 ) (5800 K) 4 = 63 × 10 6 W·m –2.
