Mist box
The mist box is used to detect ionizing radiation particles. In its most basic form, a mist box is a sealed box containing supercooled, supersaturated water or alcohol vapors. When alpha or beta particles pass through the box, they react with the mixture in the box and are ionized. At this time, the generated ions form a mist and behave like condensed particles. The alpha and beta particles with high energy generate traces of the migration path because many ions are generated along the particle migration path. These traces and traces are distinguished by their particle size. For example, the traces of the alpha particles are thick and straight, with traces of electrons being thin and often changing in collisions. When the mist box is placed in a uniform magnetic field, the positively or negatively charged particles are deflected in opposite directions according to the Lorentz force law applied to the two particles having opposite charges.
