Radiations and their interactions with matter.
The Main Idea
Radiation consists of 2 components, electric fields and magnetic fields. The question being answered is "How do these radiations interact with matter?" We know that an atom is basically a nucleus and its electron cloud, but the nucleus is so small that the chances of radiations striking the nucleus is negligible. On the other hand, the peripheral electrons stand a much greater chance (about [math]\displaystyle{ 10^9 }[/math]) of getting impacted by radiation. The denser the material, the higher number of subatomic particles which results in a greater probability of interaction.
Description of The Interaction
Energy can neither be created nor destroyed, so when a photon encounters a particles, it transfers its energy to the particle. This energy can be returned to where it came from, scattered in a different direction, or absorbed through the material. The electric field causes a force that we have studied before : [math]\displaystyle{ F=qE }[/math]
