Because radiation is silent, colorless, tasteless, and odorless, it must use certain substances to react with the radiation, and the result of the reaction can be easily measured.

Because radiation is silent, colorless, tasteless, and odorless, it must use certain substances to react with the radiation, and the result of the reaction can be easily measured. We use this indirect method to measure radiation. There are six commonly used measurement methods:

(1) photographic film.

(2) Ionizing a gas or semiconductor to produce charged ion pairs.

(3) Make the liquid crystal or crystal emit light directly.

(4) The phenomenon of "thermoluminescence" is produced by heating the crystal after receiving radiation.

(5) generate heat.

(6) An oxidation-reduction reaction occurs.
