In chemistry absorption can mean two things: Firstly it can imply that powerful forces exist holding two substances together, and that seperation of the two is not easily accomplished. Secondly it can mean absorption of heat, light etc.. . The absorption of ultraviolet, visible and infrared radiation is the basis of some forms of spectrometry which can be used to identify different chemical compounds. See also infrared radiation.

is the assimilation of molecules, or other particles, into the physical structure of a liquid or solid, without chemical reaction.
The penetration of a substance, eg. gas or thin film of liquid, into the surface layer of a solid with which it is in contact eg. process by which pesticides are taken into plant tissues by roots or foliage (stomata, cuticle, etc.).

With respect to Radiation Protection , absorption describes a mode by which Radioactive materials may enter the body leading to an Internal Radiation hazard. For example it is well known that H-3 contamination on the skin can readily be absorbed and taken up by the body water.
