Can someone explain what absorption cross section is and how it's figured into an equation? And what is irradiation?
Absorption cross section is a measure of the probability that a particle or photon will be absorbed by a material. It is related to irradiation because the higher the absorption cross section, the more likely it is for the material to absorb the incoming particles or photons.
Absorption cross section is calculated by dividing the number of particles or photons absorbed by the number of particles or photons incident on the material. This value is typically given in units of area, such as square meters.
The absorption cross section of a material is affected by several factors, including the material's composition, density, and thickness. It is also influenced by the energy of the incoming particles or photons, as well as the angle of incidence.
Irradiation can cause changes in a material's properties, such as its chemical and physical characteristics. This is due to the absorption of energy from the incoming particles or photons, which can result in structural changes or the formation of new compounds.
Yes, absorption cross section and irradiation can be used to indirectly measure the amount of a material present. By measuring the amount of particles or photons absorbed by a material, the concentration of the material can be determined using the known absorption cross section value.
